Apera Instruments 700 Series Benchtop Meters AI501 1

I use it in a scientific laboratory where pH data is critically important. I found that it is simple but easy to use instrument. The calibration is quick and simple. The results are precise. I highly recommend this instrument.

Excellent benchtop meter. Large and clear display and easy to read results. Excellent manual and laminated cheat-sheet card. Electrode stand is very convenient serving as that missing third hand. Reading stability and electrode health measurements after calibration very, very useful. Overall, a big step up from my trusty but aging portable meter. Highly recommended.

The device is very intuitive and friendly-user, reminds me to ikea stuff. The accuracy of the measurements is as expected. Only issue I found is that allways comes with an american trasnformer so you have to buy a suitable one separately.

非常に低価格で購入でき、通常の試験研究に使用される標準的ｐHメーターとほぼ同じ性能を有している。測定値の変動が少なく、一度校正しておくとドリフトが殆どないので、まず1ヶ月は校正せずに測定できる。
