Hestya Calibration Digital Balance Tweezer Review

So I'm a data scientist with access to a Mettler Toledo lab balance. I have calibrated the scale using commercial 1.00g and 1000.00g calibration weights which have a tolerance of 1.0%. The weights in this set were surprisingly accurate, only the 5.00g weight was 0.01g off. More than enough for personal use at home on a kitchen scale. Other reviewers may claim that the weights on their scales aren't accurate, but unless they're using a commercially calibrated scale, you won't know if it was the…

I was expecting them to come in at least a box but they didn't, they came in a resealable plastic bag. One of the scales I bought had a 50g weight and two cut outs for two weights, so I put two of those weights in and left the other three in the resealable bag that came with it. The tongs are good, hold the weight well. I tested the weights on two scales, one to three decimal places and the other to two decimal places. Both scales showed the same weight values. Some weights were off by about…

As for the price, the overall quality is [perhaps a little lower] than I expected; and i would probably be lucky enough to get 5 stars BUT they arrived in a bag with no tote. - Good tweezers are negated by trading in bulk and scratching the surface of the metal on the way to the buyer - that's not cool. When it comes to calibration weights, even cheap, poor quality weights turn into junk as they collect moisture and oil. Protection against contamination, e.g. B. norm-breaking exposure when…
