Combustible Gas Detector – GTYQ Series

The GTYQ Series point-type combustible gas detectors are designed for industrial and commercial use. These detectors offer simple installation and easy wiring, providing continuous monitoring of methane, combustible gases, and toxic gases within the explosion limit range in both industrial and commercial environments. The gas concentration and system information are converted into digital or current signals and transmitted to the gas alarm controller for identification, display, and processing.

Key Features

Continuous Monitoring: Designed for continuous monitoring of methane, combustible, and toxic gases within explosive limits.
Signal Transmission: Converts gas concentration data into digital or current signals for transmission to a gas alarm controller.
On-Site Display (for select models): Some models offer an on-site display feature for real-time monitoring.
Audible and Visual Alarms (optional): Optional sound and light alarm feature to signal hazardous conditions.
Infrared Remote Control Calibration and Settings: Supports infrared remote calibration, zero adjustment, and parameter settings.
Remote Calibration via Host Controller: Calibration and zeroing can also be conducted through the host controller, ensuring ease of use.
