Detection Principle |
Detection technology varies based on the target gas, with the following options available:
- Electrochemical Sensor: Suitable for detecting oxygen, carbon monoxide, hydrogen, ammonia, sulfur dioxide, hydrogen sulfide, nitrogen oxides, hydrogen fluoride, chlorine, and more.
- Infrared (IR) Sensor: Used for detecting carbon dioxide, methane, bromomethane, and petroleum gases.
- Photoionization Detector (PID): Used for VOCs, TVOCs, benzene, xylene, and similar gases.
- Catalytic Combustion Sensor: Used for detecting combustible gases such as methane, ethane, and hydrogen.
