7Pcs/Set 500g Grams Precision Electronic Balance Scale Calibration Scale Weight Jewelry Scale Weights Set Smart Weigh Kit Weigh Scales (10g 20gx2 50g 100gx2 200g)

You won't get laboratory precision for this price, so don't plan on using these to calibrate high-accuracy lab scales. When I weighed them on my lab balance, I discovered that two of the weights were slightly off - one by 0. 01g, while the other is a fraction of a gram. 02g, and the second had a smidgeon of rust on it (!). ) on it. If you require laboratory services, please contact us. If you want high-quality weights, expect to pay at least 10 times the price of this set. br>br>However, these are ideal for calibrating kitchen scales, which is why I purchased the set. Most kitchen scales are only accurate to a few hundredths of a pound. A set that comes within a hundredth of a gram is more than adequate for this application, as some are far less accurate than that. The weights are packaged in a convenient, fitted plastic case. br>br> br>I'm not sure if the plastic tweezers were necessary, but - They're right there. br>br>In general, if you need to calibrate a kitchen scale or a microbrewing scale for weighing hops, this set is a good buy.

Three of the weights were off by a tenth of a percentage point. 02, but other than that, it's a good investment. Set of weight calibration that works well.
