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.

The instructions were perfect. Easy set up and calibration and makes measuring the ph of our cosmetic products a simple and accurate process. So happy to have made this purchase.

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。

Electrode became defective after less than a year.
