Ex-proof Electrochemical Gas Detectors

Used for the sensitive detection of toxic gases and oxygen. It can detect gases such as carbon monoxide, hydrogen sulfide, ammonia and sulfur dioxide with ppm (parts per million) accuracy. Easily integrated into your security system with relay outputs, 4-20mA analog signal output and RS485 Modbus signal output.

Quick Specs

Superior Technology in Gas Detection

GDSFX Electrochemical Fixed Gas Detectors offer a next generation solution for the detection of toxic and suffocating gases. It uses electrochemical sensor technology to detect toxic gases such as carbon monoxide, hydrogen sulfide, ammonia. These sensors utilize the electrochemical reaction of target gas molecules on an electrode to make highly sensitive and specific detections.

The LCD display provides users with instant gas readings, instrument status and alarm information in a clear and easy-to-understand manner. The display’s user-friendly interface allows easy configuration of instrument settings and alarm limits. Modbus RS485 communication capabilities allow the detector to be integrated into control systems and monitored remotely, so plant staff can easily monitor multiple detectors from a centralized location.

GDSFX Electrochemical Gas Detectors can detect even very low gas concentrations thanks to its sensitive sensor. This high sensitivity and reliability is vital in sensitive applications such as wastewater treatment plants, laboratories, chemical plants and in the energy and food industry. The long-lasting design of the instrument, combined with minimal maintenance, increases operational efficiency and reduces downtime.
