The most important features

Detailed description

Designed for pH, mV, redox potential and temperature measurement. Pocket-size, easy in use waterproof meter of good technical parameters.

Characteristic features:

GPX-105s head is equipped with durable pH electrode made by australian company ”Ionode” of untypical construction. It has ”intermediate junction”, which protects the real junction (diaphragm) of the electrode against clogging, ensures stable measurements in most types of liquids or semi-liquid masses, in which other electrodes quickly stop working. The electrode's sleeve is chosen depending on requirements. When properly handled and maintained the electrode may be efficient for several years.
