WD6200-IR Fixed Gas Detector with Double Beam IR Sensor 

WD6200 Fixed Gas Detector is designed for detecting methane (CH4). It features a double beam IR sensor that effectively reduce the zero drift to the minimum, and extends the maintenance intervals. The detector enjoys better gas selectivity, stability, longer life span, and wider application over detector with regular IR sensor. It shows not only the concentration of gas but also diagnostic result of the unit itself through the LCD screen and can be connected to the control panel with a standard 4-20mA analog communication. 

Features: 

• Double beam infrared technology, good stability
• High accuracy, longer lifespan
• 4-20mA signal output
• 3 relay output for low alarm, high alarm and fault alert
• LCD display, easy to read
• Remote controller for setting, easy operation
• Special installation accessories, easy installation
• Smart sensor module design, easy maintenance
• Sensor with heating function, excellent moisture and heat resistance
