Milligram Scale with USB Supply, NEWACALOX Reloading Scale 100 x 0.001g, High Precision Portable Multifunction Lab Powder Scales with Calibration Tare Weights, Tweezers, Weighing Pans Black

I purchased TWO identical scales model 8028 series 100 g capacity in October 2018. Both arrived timely with all listed accessories including two AAA batteries, plastic tweezers, powder / liquid holding cup, 100 g weight. I chose 100 g model so I could check very tiny objects and some postal packages as well. 50g model seemed less attractive to me, even if it might do better job on tiniest objects. Maybe. This scale looks very elegant and professional, it looks as good or even better than some scientific instruments I purchase at work. Considering its price, I hardly can believe it is so accurate as specified. I decided to check accuracy and compare both scales a week later, at typical room temperature and humidity 50%. I check both scales with very little weight, where usually scales do not do well.Both scales stand next to each other, on flat glass table surface. Tiny non-slippery pads work nicely. I use two small pieces of paper as weights, turn ON both scales at a time. Calibrate both scales to 100.000 g with the same 100 g weight, start measuring both pieces of paper positioned always as close to the center as possible. I swap measured objects between both scales, while taking notes - to include any scale circuitry warming up effect if any. I do it slowly, wait about 5 sec each time, hoping to capture some reading changes or fluctuations. Here is what I got, final readings each time:SCALE A. SCALE B0.013 g 0.013 g0.014 g. 0.014 g0.013 g 0.013 g0.013 g 0.013 g-----------------------0.091 g 0.090 g0.091 g 0.091 g0.090 g 0.091 g0.091 g 0.090 g0.090 g 0.091 g----------------------0.013 g 0.013 gDuring all measurements there was no reading fluctuation, no reading noise on last digit, no reading changes except a few times final reading after 5sec was 0.001g higher than first, immediate, instant reading. Numbers above show really repetition, not accuracy - still excellent product.SMALLEST WEIGHT that can be detected. I took a small piece of Kleenex tissue. Scale showed 0.013 g. I divided it into two pieces, scale showed 0.005 g and 0.007 g initially, but I could not repeat this. It seemed 0.005 g was not detected most of the time, scale showed 0.000 g. Similar test with a tiny piece removed from a small clear packaging bag resulted in showing -0.003 g. I understood some tiny static forces influenced readings below 0.010 g. At a time, 0.013 g paper is detected very reliably! All this while full range is 100.000 g. Incredible!DISPLAY is rather large, reads nicely and easily in a bright room. Does such scale consume a lot of current? I am thinking how to check on this, as I have many gadgets at home that use batteries too quickly in my opinion. Current consumption for this scale measured gave 8.2 mA, immediately after power ON. With typical AAA battery capacity (Google "AAA battery capacity") rating 1000 mAh it seems battery life should be about 120 hours. I expected little less current consumption, but this is not bad at all - specially considering battery that is not 9V type. Interestingly market is flooded with rechargeable batteries and this scale manual does not say if OK to use rechargeable batteries. I guess no big deal in this case, considering such fact that most rechargeable batteries do not hold charge very long time.AUTO OFF function: When I started calibrating both scales, one scale went OFF after about 30 sec. The other one never did this during entire testing time. I assumed scales go OFF after 30 sec when no activity detected, otherwise they continue working.Overall I am delighted, I never thought I could have such sensitive scale for less than $25. Five stars!

I load my own ammunition and as such, accuracy and consistency are key. I have used a beam balance for years and while slow to use, it does give good results. I never had interest in digital scales marketed by the usual suspects in the sport shooting arena because their accuracy are all the same at +/- 0.1 grains. A .2 grain variance on my loading bench is a LOT and is unacceptable. I normally weigh small quantities of propellant; 25 up to say 45 grains is typical. So, when I saw an advertised accuracy of +/- 0. 02 grains, I was interested and ordered this scale. There is a whale of a lot of difference between .04 grains and .2 grains!This little digital balance does the trick for me. However, there are a few 'how to's' I recommend. Here's what I have found works best for me:1. When adding propellant to your tray, you will see the value displayed on the scale continually increases as you'd expect. However, if you lift the tray off the scale, allow the scale to settle and place the tray on the scale again, the value shown will be higher than what you started with. My solution then is to lift the tray off the balance when my target weight is close (but lower of course) and allow the scale to settle, replace the tray and trickle in a few pieces of propellant, lift and replace the tray again and allow to settle. I quickly got 'good' at doing this and this method is actually easier and faster than using my tried and true beam balance.I have seen zero drift on any value thus far. It displays a consistent value until it times out.CON: I wish there was some way to disable the auto off function. I think it's about 30 seconds as is. When I first started using the scale, it would auto off before I was finished weighing and I'd have to start over. The method I described above will keep the scale active. i.e. I loaded 11 x .308 rounds today, one at a time and the scale never timed out on me.Definitely recommended! Good luck and keep 'em in the X ring!

The scale itself is perfect, but the user manual is weak and the TARE button is useless (and dangerous). DON'T USE THE TARE BUTTON ON THIS SCALE!!Pros: The impressive range of 0.001 g to 200 g is unique among milligram scales; most only go from 0.001 g to 50 g. That's 4 times the standard range! It's also amazingly accurate throughout this wide range. If you need something more accurate, be prepared to pay HUNDREDS of dollars for a laboratory-grade scale that can measure to the nearest 0.0001 g (nearest 100 mcg). Most people will never need that kind of accuracy, unless you're dumb enough to use fentanyl (in which case you're probably too dumb to use a lab scale in the first place).Cons: The instruction manual is vague on several points. I had to watch the video in the product description in order to properly calibrate the scale, but that's forgivable. The TARE button is an accident waiting to happen (gives both false high and dangerously low readings. Only use the TARE button if the the scale does not show 0.000 with nothing on it -- NEVER use the TARE button for an empty vessel (which is what it's designed for). After doing some research, I found that two other brands of milligram scales have the same issue with the TARE button.

Scale is small, easy to use & calibrate, seems accurate, durable compared to other similar scales. Batteries easy to replace, but have only needed to replace once a they last a long time (Enerergizer). Would recommend
