Electrochemical Gas Detectors

For the precise 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) level accuracy. Easily integrated into your security system with relay outputs and 4-20mA analog output.

Quick Specs

Gas detectors with electrochemical sensors are suitable for the detection of toxic gases and oxygen. They are used for highly sensitive detection of gases such as carbon monoxide, carbon dioxide, hydrogen sulfide, ammonia and sulfur dioxide.

GD2G Electrochemical Fixed Gas Detectors feature an advanced microcontroller chip on a smart circuit board. The embedded software algorithm guarantees perfect detection under all conditions. It also allows software optimizations according to the needs of your plant.

GD2G Electrochemical Fixed Gas Detectors can be used as a standalone device with digital relay outputs (NOC) or easily integrated into your control and automation system with industrial standard 4-20mA analog outputs. It reacts instantly if target gas is detected at the lower and upper alarm limits you set. Dangerous situations for the safety of your personnel and your facility are prevented before they escalate.
