Profile

potential electrolysis type. Oxidation-reduction

reaction with hydrogen and oxygen take place

respectively on the working electrode and on the

counter electrode. The process releases electric

charge and generates current. The current is in

direct proportion to the concentration of

hydrogen. So the concentration of the target gas

could be got by measuring the value of current.

Features

Low power consumption, high precision, high sensitivity, wide linear range,

good anti-interference ability, excellent repeatability and stability.

Main applications

It is used for hydrogen detection in industrial occasion and environmental protection field.
