Electrodes

pH Electrodes
Our pH electrodes have a broad line-up according to sample, container and application type.

Metallic Electrode(For ORP Measurement)
Waterproof. Use a flat type metallic electrode, which allows a small amount of sample to be measured.

Ion Electrodes
HORIBA's years of experience and know-how in this field are behind the wide range of ion electrodes we offer.

Conductivity Cells
HORIBA's conductivity electrodes also have a built-in thermistor for temperature measurement, making them perfect for for temperature measurement and for obtaining values equivalent to those at the standard 25℃ when used in conjunction with the conductivity meter.
