Wireless pH sensor

Description

The pH sensor can be used wirelessly via Bluetooth or wired via USB with the Coach 7 or Coach 7 lite programs/apps on computers (Windows and Mac), Chromebooks and mobile devices (Android and iOS).
The pH electrode is supplied in a storage bottle containing a protective solution. When it is not being used, it must be kept in this storage solution. During measurements, the electrode must be dipped in the solution for about 1 cm.
