The MIC-600 Series Fixed Multi-Gas Detector is a high-performance online gas monitoring device designed for 24-hour continuous monitoring of multiple gas concentrations along with temperature and humidity measurement.
It features a 2.5-inch high-definition color display for real-time visualization of gas concentration, alarm status, temperature, humidity, and system information.
The device integrates internationally recognized gas sensors, including detection principles such as:
Electrochemical
Catalytic combustion
Infrared (NDIR)
Thermal conductivity
PID photoionization
A Swiss high-precision capacitive digital temperature and humidity sensor is also available.
The MIC-600 detector is suitable for monitoring pipeline gases, confined spaces, atmospheric environments, gas leakage detection, and high-concentration gas purity monitoring. It supports detection of more than 500 types of gases.
Its explosion-proof enclosure and fluorocarbon coating provide excellent resistance to corrosion, wear, and harsh industrial environments.
