Double beam infrared technology, good stability
High accuracy, longer lifespan
4-20mA / Hart signal output
Measuring gas: CH4, C3H8, C4H10
Measuring range: 0-100%LEL
Measuring accuracy: ±3%LEL
Sensor life: ≥5 years
EST-WD6200IRII Fixed Gas Detector is designed for detecting flammable gas. 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.
