Bonvoisin Lab Scale 5000gx0.01g High Precision Electronic Analytical Balance 0.01g Accuracy Laboratory Precision Digital Scientific Scale (5000g)

5000gのはかりを講入し、2000gの分銅で校正後、10mg～1000gの分銅を使用して表示される数字を確認したところ、50mg～1000gの分銅で非常に正確な数値を叩き出しました。びっくりです。なお、10mg、20mg、そして20mg×2の板状分銅を載せた時は「0.00g」と表示されましたが、5000gのはかりで50mg未満の重さのものを量ること自体がナンセンスですね。ちなみに、10gと10mgの分銅を載せた時はちゃんと「10.01g」と表示されました。 また、説明書には、校正用分銅(2000g)が重すぎるため、輸送中にはかりに損傷を与える可能性があり、校正用分銅が付属されていないと記載されていますが、別送で校正用分銅をできるだけ格安で提供していただけるサービスを選択できるようにしていただきたいと要望したところ、即日、社内調整をされて、ほぼ1週間でM1等級の2000g校正分銅がアマゾンで販売開始されました。素晴らしい企業風土だと感じました。

Me acaba de llegar..... lo justo seria hacer una reseña pasado un tiempo de uso pero me ha gustado tanto que me apetece decir lo precisa que es , la utilizo para pesar la comida y suplementos ya que entreno y soy nutricionista , espero que siga siendo perfecta en el tiempo.

I love these things, great for measuring everything from my cat to rolls of filament after drying to see how many milligrams of moisture has been removed, to anything else in my lab that does not require milligram accuracy. They are sold under probably a half dozen different gibberish-name Chinese vendors but they all come from the same factory. They have a hidden menu that allows you to change settings that are explained nowhere in the manual - if you are the curious type of person who likes exploring into digital systems you should be careful as I changed it from a 5 kg max/0.01 g resolution scale to a 100g max / 0.001 g setting. Of course the load cell did not cooperate and there are about a hundred different options to choose from which are anything but clearly described in the menu. Long story short it took me a couple hours to get it set back correctly but I really wish the manufacturer would not give instructions on how to access a menu and then only explain a couple of the functions! (Not that I wouldn't have found the menu on my own, but still...) Overall I'm very happy with the purchase and have ordered three of them for different locations.

Pretty good scale, considering the relatively low price for a 'lab' grade scale. Seems to provide consistent weighing. Easy to recalibrate with 2kg weight (bought separately). Nice large illuminated digits. Removable weighing platform which is handy for cleaning. Operates off 120V, not battery (manual says battery is for emergency use only and will operate for only 30 min.) which is good for my purposes. Some quality issues such as razor sharp edges on the flanges of the weighing platform...needed to 'break the sharp edges' myself using a file. The membrane switches are not the highest of quality but do seem to work well (personal peeve, I do not like membrane switches).

Amazing scale with such accurate measurements! Would recommend anyone.
