Weighing Scale - pocket scale, american weigh


Click here for more information
This scale is a great value for the .01 gram precision it offers. Once calibrated it is quite sensitive and accurate. Mine came quite far from calibrated, but based on the other reviews here it appears this is only a fluke. The scale is lightweight and very portable, being roughly the same size as a Nintendo DS Lite. Build quality is good; it looks like it will last a long time if used properly and carefully. Comes with two AAA batteries and a space for storing a pair of extras. Very nice scale for the price.



One hint about calibration: if you forget to buy the 100g calibration weight, you can simply use 20 U.S. nickels, as each nickel is exactly 5g.



I purchased this exact scale from this seller for reloading. Its important to have .1grain resolution, as is advertised. It does not, its .2grain. Contacted seller (scales n tools) they said that it was a manufacturing change and offered to take it back. Fair enough. They still havent changed the ad on here though, so they are purposely misleading people with false advertising.

I've had this scale for a couple years, and I'm very happy with it. It's accurate, repeatable +/- 0.02 grams on different days, and has held up through moderate handling (nothing abusive, but stuff that I'd never put my lab scale through).



It uses what I call a "floating zero". This is good and bad... When within 0.03 grams of zero and steady, it displays 0.00 and slowly adjusts its zero. If you slowly add 0.01 grams at a time, you can get it to drift way off, and when you eventually take off all the weights at once, it'll display -0.20 grams or whatever their weight was. The good is that the scale, despite its inexpensive mechanism, keeps very good zero calibration between measurements. The downside is that it makes small measurements difficult. If you want to weigh out 0.15 grams of powder, you can't just tare your weigh paper and then gradually pour it on - the zero will drift unless you add the first 0.05 grams quickly enough. Instead, you can NOT tare it, and manually subtract the weigh paper.



This feature is not a problem at all unless you're weighing very small (less than 0.1 grams) items on a regular basis. I think this is an acceptable compromise for a pocket scale of this precision at this price (and it's practically standard until you get to much more expensive equipment), so I am not marking any points off. - Pocket Scale - American Weigh - Coins - Kitchen Scale - Digital - Dw

I purchased this scale to weigh chemicals for amature rocketry. The biggest problem that I have run into is that the power save feature turns off the scale while I am still adding chemicals to the weight dish. When you turn the scale back on, it zeros itself out. It slows me down alot. Other than that, it has worked fine so far. For the price, I'd say it's a good deal.



It's accurate and would be good for a wide variety of uses. It's nice that it takes 2 AAA batteries instead of the expensive flat round ones that die out very quick. For some reason the expensive scales (over $20) always seem to use these batteries.



It's definitly a good scale at $8...if you want something nicer with a stainless steel weigh surface spend $20 or more on a better one. The scale is ALL plastic and made in China, so know that before buying.

The little scale turned on with no problems, but I quickly realized that it was giving results that were very inaccurate. It would measure 10-15% less than a calibrated scale. No problem, I thought, as the instructions said it just needed a quick calibration. The problem, the ONLY way to calibrate it is with a 500g weight. My calibration weight kit does not contain this, and to purchase this weight is 2 to 3 times more than the cost of the scale. Defeats the purpose of an economical, small scale. I'm giving it the benefit of the doubt by giving it 2 stars, with the assumption that it may be accurate if it came calibrated. I'm off to buy a different scale now..

First of all, after retrieving the mail, I noticed a small package, I got really excited and though it was my 20mW green laser, but it was actually this scale. It was 100x smaller than i thought it would be! When they say "pocket scale", they mean it! This thing is smaller than my wallet, but a little bit thicker. Gets the job done for me, weighing out chemicals for backyard pyrotechnics and the like.



Pros:

+ 500g capacity, with .1 resolution, aka: 35.7g as an example reading, but also has oz, dwt, and ozt modes.

+ tray that doubles as cover to keep dust out

+ tare/zero and calibration functions

+ small! fits just about anywhere

+ bright backlight and easy to read numbers

+ simple to operate, ready to go right out of the box with included batteries!

+ 2 AAA batteries, not those rare button types!

+ black color and fairly easy to clean

+ made of plastic, nice and light

+ gets the job done!



Cons:

- its very small size might make it hard to weigh bigger containers/items [but im sure you could figure a way around this, something flat, tare/zero function...]

- someone else pointed out the scale auto-powers down after a short delay, which can happen while you mentally calculate how much more you need to add.

- a super slight deviation at times, such as: 45.3g then after several seconds shows 45.4/45.2g and then goes back to 45.3g. [so if you need absolutely precise measurements, you need to go look for a professional scale], this is a non-issue for me, one decimal precision is much better than +/- 2 whole grams...

- it is made of plastic, so dont expect to drop it off a table multiple times and have it be accurate, but the price makes it a no brainer to just buy a new one



All in all, this is an awesome deal! I am very tempted to buy 2 or 3 more if I find some money...HDE was very quick, 3 whole days before the expected delivery time, and received the exact product as advertised. Its the performance you would expect from a product 3-5x the price [yes including shipping].



If you need a very small portable scale that works, look no further!

For a small inexpensive scale this one works great. It is very sensitive and does a great job for a pocket sized scale. Be carefull to make sure you have the weighing tray centered on the weight sensor though, with it's high level of sensitivity it is easy to get a false reading if you do not have the tray in the right position.

for the price you can't beat it. the scale works as it should and would recomend it to anyone looking for a digital acale. i have owned quite a few scales in the past in which i paid in upwards of a $100, this scale is just as could a a fraction of the price.

I purchased this scale so I could weigh small packages/envelopes and print out USPS First Class Mail (FCM) shipping labels with exact weight in ounces. I'm glad to say that this scale has not disappointed me.



If you print out your own USPS FCM labels online then you get free Delivery Confirmation so this scale has already paid for itself at least 3 times over. Before I was going to my local post office and purchasing Delivery Confirmation for .90 cents for each package but now with this little wonder I can weigh my own packages and save cash. If you mail several small packages every week via FCM then the savings really do add up.



Despite it small size (2 1/2" wide x 3 1/2" long) it can weigh large envelopes because the cover also acts as a supporting tray. If you mail 8" x 13" bubble wrap envelopes frequently like I do then this scale will be perfect.



I'm very happy with my purchase and I would highly recommend this item to anyone who is looking for a quality scale at an economical price to determine if their packages qualify for USPS FCM. - Pocket Scale - Digital - Fast Weigh - Kitchen Scale - Office Electronics - Coins

Measuring Tools - pocket scale, american weigh


Click here for more information
I bought this unit to weigh gold and silver coins and bullion. It's a very sturdy yet compact unit. It fits in a pocket or purse or any bag. It seems to be very well made and the scales are accurate.



When I first got the unit and turned it on, it didn't work. I discovered the batteries were loose. Actually, the batteries should be outside the unit when shipped.



In any case, while I've not owned them long, I'm very pleased with them. The price is exceptional and EZ Sales are just super to deal with.



I was a bit annoyed that the unit did not come with a calibration weight. Be sure and get the 500 gram weight for this model. You won't need it the first time you use the unit, but at some point, you will.



Highly recommended.



Update: After using the scales for checking coin weight for awhile now, I've noticed that it's not totally accurate. Even after calibration. A silver dollar should weigh 31.1 grams. I have them weigh from 31.1 to 31.5. But the troy ounce is always 1oz, as it should be.



There is a margin of error. So if you need extreme accuracy, you'll have to spend a lot more money. But if you want to be just quite close, this will do fine.



I ordered this scale to weigh small parts for RC cars and it has performed excellent. As others have mentioned you need to remove the batteries from the unit before using the scale because the batteries are shrink wrapped in plastic. For the price I didn't expect the build quality to be great so I wasn't shocked at the fairly cheap build quality. The plastic casing feels ok but the battery cover feels cheap and loose. The protective cover for the stainless steel weighing platform is not too bad though. The scale is small about 4" x 3" in size but the weighing platform is decently sized covering about 70% of that area.



In terms of ease of use and accuracy it's a great little scale with a nice sized backlit LCD with an auto shutoff to conserve battey power. To get accurate results you need to place it on a flat non-moving surface because this scale is VERY sensitive. I've found the scale to be very consistent by weighing the same objects many times and the results were always within +/- 0.1 grams for small items that are less than 30g. The scale comes ready to use and calibrated from the factory, however if you ever need to recalibrate this model you will need to use a 500g calibration weight, you cannot use smaller calibration weights because they will not calibrate correctly. Also keep in mind that environmental factors will affect the scale readings such as ambient temperature, strong drafts from ceiling fans and magnetic fields.



This is a precision instrument so should be adequately taken care of eg don't drop it, don't let it sit in direct sunlight, don't keep it in high humidity areas and also store the scale lying flat not vertical. All in all a great low cost and accurate pocket sized scale that is very easy to use.

The price was excellent. The scale works well, and I haven't noticed any of the inconsistencies noted by other reviewers.



The clamshell cover and stainless steel scale plate are excellent features, as is the 'indiglo-style' backlight to the display, which was an unexpected, though very welcome, surprise, and the batteries were included (also a nice surprise these days).



I, too, noticed that the batteries were crooked and the unit didn't work immediately when I opened the package, though this appears to be deliberate to keep the batteries from draining while in transit. Once they are unwrapped (mine were shrink-wrapped, and installed in the scale fully wrapped), the scale works fine.



All in all, it is very nice, quick and easy to use, and took precisely two days to get to me with standard shipping -- astoundingly fast service.



I'm very satisfied with this purchase.

The scale is constructed quite nicely, and the black casing with stainless steel weighing pad adds for a nice polished look. It comes with batteries (which I discarded because they were a nameless Chinese brand) but the thought of adding batteries free of charge is nice. In the battery compartment there is a place to store an extra set of batteries (which I do, it makes it feel weightier/higher quality). It's very slim and is easily stored. Instructions are printed on the inside of the lid which is nice. Another reviewer said not to calibrate it, but I purchased a 500 gram calibrating weight and did it just to see if it would work okay and it did. The scale said 500.6 grams before I calibrated it, so it was fairly accurate to begin with and most likely won't require calibration for a while. Good looks, accurate and repeatable results, excellent price, what more could you want in a 600 gram scale?

When it was working it was flaky. It would weigh the exact same thing out differently . (Margin for error was about .2 of a gram for every 5 grams on the scale.) After just a few uses, It said the batteries were dead. (came with some cheap generic chinese batteries) When I opened up the compartment, one of said batteries had been leaking battery acid all over the inside of the scale. Needless to say all the metal parts were rusted out and it never turned on again. BUYER BEWARE THIS IS A SUB PAR PRODUCT. - Pocket Scale - American Weigh - Kitchen Scale - Coins - Jewelry - Digital
