3000g x 0.01g Lab Analytical Balance Scale, MOCCO 10 mg High Precision Electronic Scientific Scale Accuracy Weighs Laboratory Instrument with 500g Calibration Weight, Adapter for Laboratories School

A very complete, well thought out and accurate scale set. Tremendous value.

Bright screen; stable read; accuracy is good for the calibration weight provided. Excellent packaging btw! The top cage is a bit low - but it works fine without it.

I have bought this exact scale from Ebay just because the price was much lower than on Amazon. Mine has a LEADZM logo, but I believe it is the same 3000/0.01 g scale. It came nicely packed with no shipping damages. It also included two 500 g calibration weights. Initially before calibration they measured 500.44 and 500.43 g on this scale. Regardless what sellers may tell you all precision scales and balances must be properly calibrated at the place where they will be used. Shipping and ambient conditions will affect the accuracy, that is why calibration needs to be done as often as practical. Calibration weights shall be more accurate than the scale.Since nobody could tell me which weights are required for calibration, I have prepared all precision weights I have. After leveling the scale, warming it up for a couple of hours I pushed the "CAL" button for a few seconds and display showed me 1000 g - this is what's required for calibration. I could have used the supplied 500 g weights, but decided to use 1 kg CL.3 weight I had. After a few seconds the calibration was complete. I have weighted all precision weights I have on this scale and did not have a deviation more than .02 g from 500 mg to 3000 g weights. Although the specs were not published for my scale I think it is well within the acceptable tolerance for an inexpensive scale.Pros:-It is accurate, inexpensive, well constructed.-You can select any of the following units: g, ct, oz, ozt, lb, N, dwt, dr, GN, tlT, T, T/A/R, %.- It comes with external power supply and stays on until you push the OFF button.-The display has a white backlight (it is on all the time).-It is quick and stable and automatically returns to 0 when it detects no load.-It has 4 leveling legs. The threads are loose, but I like it that way - easy to adjust.-Calibration weights were supplied and they were of decent accuracy.Cons:-It comes with a 5 pc plastic wind shield, but it is difficult to use and not really needed inside the building.-The pocket for a 9V battery is too small, you can barely install the battery and close the door. I have a feeling that constant backilight would drain the battery in no time and external power supply feels much better.- The external power supply is 12V, 1A (input is 100-240 VAC). I can actually measure 12.5 VDC output. It works, but I have some concern that it should have been a 9V output.-The manual is just one page with no pictures. The English language is half-decent, although there is a phrase I do not understand: "Please switch the balance pan according to the direction of hour and if you want to remove the pan. Do not lift up directly".Overall I feel It is a good purchase. The scale is very functional and a few drawbacks it has can be ignored.

WARNING: You have to recalibrate it EVERY TIME YOU TURN IT ON! If you use it without recalibrating first, it will read double the expected weight/mass. You might think you can just weigh things and divide by two, but that gets messed up if you want to tare the scale. Also, it defaults to calibrating with 2000g, but only comes with 1000g of weight for calibration. So, not only do you have to calibrate it EVERY TIME you turn it on, you have to mess with it to get it to calibrate to 1000g instead of 2000g (unless you have an extra kg lying around). Also, for some reason, after two batteries were used up, new batteries completely stopped working and I have to use the AC adapter. Also, none of this is in the very poorly written instructions.

Very accurate and easy to use

Seems to be a nice scale, I bought it to balance my pistons. Didn’t come with the calibration weights, and slowly increases weight without additional weight being applied. Maybe because I need to calibrate it, but of course it can’t.

It refuses to measure anything less than 200 mg and I'm not sure that it's getting that one right either the heavier the more accurate it is but if you're trying to measure out a daily dose of zinc you will find yourself puking in the bathroom within a half an hour this I learned from experience unfortunately 🤮

My husband tells me every few days how much he loves this scale! It is accurate and has made measuring ingredients for our cosmetic business so much easier.
