QP Calibration Weights 1000g, 8PCS OIML Class M1 Precision Scale Weight Set

This is a great set of weights for verifying the calibration of your kitchen scale. Probably not precise enough for drug prescriptions or use in commerce, but more than enough for use in cooking and mixing drinks. I tested the set on my new kitchen scale, and the weights were within 0.5%. I think it is a good buy.

Bought 2 of these 200 gram weights to calibrate a pocket scale and they are both spot on at 200g a piece.

Effortless from order to delivery - in Kenya! Really good and very happy with the product

works perfect

My box was short by one 20-gram weight. There should have been two 20 gram weights. I purchased the calibration weights to check the calibration on my kitchen scale. According to my scale, all the weighs agreed with the readout on my scale, except the the 500 gram weight, weighed 500.5 grams. or appeared to be high by 0.1 percent. That's not good enough for scientific measurements, but probably good enough for baking. Should I send the whole set back for a replacement? At least, I want the second 20 gram weight.

Awesome product

PERFECT! Exactly what I needed.

Weight was precise and cut from quality steel. Worth the price

I bought these, like many others, to check the accuracy of my home scales. I checked them on our kitchen scale and if they were the exact weight as shown on them, then the scale said they were bang on. That's assuming that my kitchen scale is reading correctly. Either way they were close enough for me to use. I'm now using these weights to calibrate a 3D printed filament scale made from a 1kg beam load cell, an Arduino Nano board and an OLED display. Nice to get a good idea as to how much filament is remaining on the spool before committing to a print. Good value for the money.

10g = 10g 20g = 20g 50g = 49.8g #1.100g = 100g #2. 100g = 98.9g 200g = 200g 500g = 499.3 G These simply cannot be used for accurate weighing or calibration purposes. Return initiated.
