QIWEI PHS-25B acid alkalinity Tester (desktop precision) rechargeable

Introduction

Qi WeiPHS-25BThe pH Tester has a measurement accuracy of ±0.05pH. Simultaneous measurement of pH and mV is available with a white backlight. thereintoPHS-25B（Rechargeable）Yes, the battery can be installed inside the pH meter, you can use the power cord or unplug the power cord and directly use the animal battery to support the work of the PH meter, which is easy to operate, and the battery can be used for 10~15 hours after a charge.

Note: The original model of PHS-25 is PHS-25C,The original model of the PHS-25C was PHS-25CB。

Product principle

PHS-25 (Desktop Precision Type) / PHS-25B (Desktop Precision Rechargeable) pH Tester converts the activity of hydrogen ions in aqueous solution into electrical energy by a sensor (pH composite electrode), and the electric energy is input to the PH meter, which is converted into digital display by A/D after op amplification and current detection.
