GTYQ-WD6200IRII Fixed Gas Detector

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



GTYQ-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.
