Overview
NL5-T3 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.
Key Features
- Low power consumption
- High precision
- High sensitivity
- Wide linear range
- Good anti-interference ability
- Excellent repeatability and stability
Applications
It is used for hydrogen detection in industrial occasion and environmental protection field.
