HFS(R) Calibration Weight Set 1000g with Case and Tweezers for Digital Scale, Gram Scale-M2 Class Precision 8pcs 10g,20g,20g,50g,100g,100g,200g,500g

⭐⭐⭐⭐⭐ The HFS(R) Calibration Weight Set is an exceptional tool for anyone needing precise weight measurements for calibration or testing. The 1000g weight is impressively accurate and comes in a well-designed case that keeps everything organized and protected. The weight itself is solid and robust, providing reliable performance for ensuring the accuracy of scales and other measurement instruments. The case is durable and compact, making it easy to store and transport the weights safely. For professionals and hobbyists alike, this set delivers the precision and quality needed for accurate calibrations. If you require dependable weights for your measurement tasks, the HFS(R) set is a top-notch choice. Highly recommended!

In all honesty it's a really good bang for your buck for what I use them for the weights work perfectly. The tweezers that come with it or kind of useless they're just too chintzy and you can throw those in the trash. For the price I'm not sure exactly what someone is to expect, it's basically a standard case to hold the weights which to me is no big deal this item was a great buy and a great value for all the different weights that come with it. The scales that we use only go to the hundreds so anything smaller than that doesn't necessarily matter to us.

This calibration weight set is very well made. It was checked against a weight and trades certification set. While this set it wasn't exactly the same weight it was well within tolerance for accuracy.

Some oil or other marks on some of them, but this is a $20 set. They seem more accurate than my kitchen scale can measure. I will use them to calibrate my scientific scale. If you're reading Amazon reviews to determine if standards are good enough for your purpose these are good enough. If you bought a scientific scale because you needed a scale that could do tenths of a gram for pinewood derby weights like me, this is a good set for calibration as well as using for a lesson on weights, measures, standards, accuracy, precision, and taking measurements for lab purposes.

For most of us using this we're calibrating a consumer-level weight scale. We're not scientists with their thousands of dollar calibration weight sets. So with that said, this unit is more than acceptable for what we regular people are using it for. It is the weights they state, so what more could I want? I think the price is great, and it works well for its intended purpose. Oh and the tweezers they include are not that strong.. They do not want oil from your hands to touch the weights (corrosion).. so just use a paper towel or tissue when you pick them up. Other than that I'm glad that an affordable kit is out there!

All calibration weights are accurate within +/- 0.1 g tolerance

I used this set and another small set of masses (0.1g to 100g) to calibrate an old Mettler P1210 scale (0.010 gram accuracy). Due to the way the Mettler is built, it has great internal reference masses for multiples of 100g. Also, between both sets I had an impressive assortment of 10, 20, 50 and 100g masses which could be combined to make 100 gram units to compare against the internal reference masss. Short story is everything measured within the accuracy of the scale. Any combination of masses measured as expected with and well within the accuracy of the scale (0.01 grams). It would be nice to weigh the set on a known scale, but to the limits of my testing I found these masses very accurate.

very good

Excelente productor tal cual se ve en las fotos y descripcion

商品は10g×1個、20g×2個、50g×1個、100g×2個、200g×1個、500g×1個と言う組み合わせで合計8個で1kgになる分銅セットです。 分銅の組み合わせ次第で10g分解能で使えるため必要最小限のセットと言った感じで商品全体の軽量化にも貢献していると言えます。 当方では最大200gと300gまで測定可能な0.001g精度の精密はかり2台で10g、20g、50g、100gを確認した限りでは、0.01gの桁でズレがある分銅もあったものの僅か0.1%未満の誤差のため計測器自身の表示誤差なのか分銅自身の精度なのか判断が付きにくいほどで、分銅の表示に対し「誤差なし」と言えるレベルの商品でした。 簡易ピンセットも付属しており商品自身は満足いくものだったけれど、青色のケースが今一歩で「落とさないようケースの裏側を持つと凸凹しており指が痛い」「500g分銅より10g分銅は小さなためケースを上下にしたり倒したりすると10gや20gの分銅がケース内で飛び出ている」と言った感じでした。 ケースやクッション材がもう少し工夫されてあるといいなと思いました。 いずれにしても分銅としてまったく問題なく使える商品のため総合評価は★5としました。

Great assortement of kit and weights. It's generally very accurate; the margin of error is never more than 0.02 or 0.01 for me.

He comprobado la precisión de las pesas y las 8 cumplen con la calibración M2 (adjunto tabla).

Los pesos son clavados. Los probé en la báscula que tiene 3 años y me oermite comprobar que funciona correctamente y no estafo a nadie.
