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

It is as advertised worked to balance scale

Liked everything

Whats to say.. it looks good although I have no way to verify accuracy

Whats to say? Its nicely made, finish is great, no imperfections. I have to take their word that the weight is accurate. Ive used it to calibrate both my scale for coffee.

The OIML M1 specification this weight claims to meet specifies the actual weight of this would be within 0.005% of the marked weight. For a 200g weight, that means +- 0.01g, so this should weigh between 199.99g - 200.01g . But of course the question is, how does one know? You need a proven already calibrated scale to determine that. So you are relying on the manufacturer of these - which all come out of the same factory it seems.

Needed it to calibrate my Triton t2 300 gram Scale

Calibrated my digital scale using this weight. After calibrating the scale I checked the calibration using 20g and 30g weights. Right on the mark. If youre looking for an accurate weight at a good price this is the one to get. Highly recommended.

Good for calibration

This weight is perfect! True to size and weight! Happy with purchase!
