Overview
NL5-KG carbon monoxide gas sensor is constant potential electrolysis type. Oxidation-reduction reaction with carbon monoxide 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 carbon monoxide. So the concentration of the target gas could be got by measuring the value of current.
Key Features
- Low consumption
- High precision
- High sensitivity
- Wide linear range
- Good anti-interference ability
- Excellent repeatability and stability
Applications
It is used for carbon monoxide detection in industrial occasions such as petroleum and petrochemical occasions, metallurgy, mine and environmental protection.
