Truweigh Calibration Weight 200 Grams - Oiml Class M1 - High Precision Grade - Calibration Weight - Calibration for Digital Scale - Weight Set for Digital Scale Gram - Calibration Weights

Perfect accuracy

Exactly what I needed to calibrate my digital scales in my small, professional kitchen. I only wish it came in a storage box. It is small, so might be easily misplaced. But at this price, I really can't complain.

I purchased this as a weight standard for my portable travel scale and it works beautifully. If you need a 50 gram standard...this will do nicely. Ciao - SS

Bought this after discovering my kitchen scale was off while meal prepping. I now use this each time to ensure my calorie counts are accurate.

When I purchased the AMIR Kitchen Scale (500.00g maximum, requires a 100g calibration weight), I attempted to create a calibration weight using pre-1965 nickels from my coin collection. US nickels are supposed to be 5.00g, but I found them to have a range of 4.90g to 5.10g with a few outliers +/- 0.20g. Using individual weight readings compared to total readings and recalibrating, I was close, but when this weight arrived, I had a reading of 100.47. Once I had it properly set, I created a second calibration weight using a plastic Coinsafe tube and 17 carefully chosen nickels for fun. It turns out the 100g weight is perfectly sized to fit in the tube on top of the nickels, and once the cap is on, it reads as 200.00g. This is how I'm storing the weight. I now have high confidence that my scale is accurate at least to the 200.00g mark.
