Review on 🔬 High Precision Milligram Scale with USB Cable - NEWACALOX Reloading Scale 100 x 0.001g, Portable Multifunction Lab Powder Scales with Calibration, Tare Weights, Tweezers, and Weighing Pans - Gold by Joe Garczynski

I bought this scale on December 14, 2020. NIST calibrated and traceable weights (I work in a lab). I did a full calibration. The numbers are shown in the picture and below. The linearity test shows that the response is good up to 20 mg, below that the response is negligible at best and no response at worst. The effective range is from 20 mg to 100 g. The angular load test shows well that the scale is quite accurate even with off-center loads. The reproducibility test shows good measurement reliability. You should get the same response each time +/- 1 mg. I would love to be able to measure to within 1mg, but these scales cost a lot more money. Calibration form analytical balance Analyst: D.
