Principle Introduction

MEWOI-MIX8423 is an electrochemical PH3 sensor developed by Mixsen. It uses the principle of electrochemistry. There is a reference electrode inside the sensor, which greatly improves the stability of the sensors. When the sensor senses the phosphine, the working electrode and the counter electrode react with the redox reaction, through measure the current to get the concentration of phosphine.

Features

High selectivity & sensitivity to PH3
High accuracy
Linear output

Application

Industrial monitors leakage detection
Smart grain storage
