Products Description

 

4S-H2S type sensor is a constant potential electrolysis type H2S sensor. H2S and O2 undergo corresponding REDOX reactions at the working electrode and the opposite electrode and release charge to form a current. The current is proportional to the concentration of H2S. The concentration of H2S can be determined by testing the current.

 

Features

 

Low power consumption and high precision High sensitivity and wide linear range Excellent repeatability and stability

 

 

Applications:

Widely suitable for industrial, underground and environmental protection hydrogen sulfide detection
