Production Description:
ME4-H2 hydrogen gas sensor is constant 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.
Feature:
Low consumption
High precision
High sensitivity
Wide linear range
Good anti-interference ability
Excellent repeatability and stability
