Gas detectors with electrochemical sensors are suitable products for detecting toxic gases and oxygen. They are used in the detection of gases such as carbon monoxide, carbon dioxide, hydrogen sulfide, ammonia and sulfur dioxide with high sensitivity.
GD2G Electrochemical Fixed Gas Detectors have an advanced micro-controller chip in the smart circuit board. Its embedded software algorithm guarantees perfect detection under all conditions. It also enables software optimizations according to the needs of your facility.
GD2G Electrochemical Fixed Gas Detectors can be used as an independent device with digital relay outputs (NOC), and can be easily integrated into your control and automation system thanks to its industrial standard 4-20mA analog outputs. It reacts immediately if target gas is detected at the lower and upper alarm limits you have specified. Dangerous conditions for the safety of your staff and facility are avoided before they grow.
