Reliable Detection
GD2G Series
Delivers high-precision, continuous monitoring of combustible hydrocarbons (LEL) and Carbon Dioxide (CO2), ensuring stability even in fluctuating environmental conditions. Engineered for seamless integration into your facility’s safety infrastructure, it connects directly to industrial control systems, such as PLC, DCS, or SCADA, via standard 4-20mA analog signals and relay outputs for immediate alarm reporting.
Quick Specs
The GD2G Ex-proof Infrared Gas Detector delivers continuous monitoring of combustible gases in high-risk industrial environments. Engineered for durability, this fixed point infrared gas detector ensures superior reliability in Zone 1 and Zone 2 hazardous areas.
Utilizing advanced infrared (IR) technology, the GD2G is specifically designed for challenging applications where sensor poisons (like silicones, sulfur, and halogenated hydrocarbons) or low-oxygen levels are present. This optical sensing method ensures long-term stability and accurate readings in conditions that would typically stress standard pellistor-based units.
The unit seamlessly integrates into your existing safety systems via industry-standard 4-20mA analog output or relay contacts, providing immediate visual and audible alerts before gas concentrations reach dangerous LEL (Lower Explosive Limit) levels.

Engineered for environments where standard sensors fail
The Challenge: Silicone and lead vapors found in paints rapidly “poison” traditional catalytic sensors, causing them to fail blindly.
The Solution: The GD2G IR uses optical infrared technology that is completely immune to silicone poisoning, ensuring continuous protection in automotive and industrial painting operations without the need for frequent sensor replacement.
The Challenge: Biogas production areas often have high concentrations of Methane (CH4) and low oxygen levels. Catalytic sensors require oxygen to work and can burn out in high-gas environments.
The Solution: Our Infrared sensor requires no oxygen to operate and can accurately monitor Methane levels up to 100% LEL (and even %Vol) in anaerobic digesters and sewer lines, providing reliable “fail-safe” monitoring.
The Challenge: Harsh outdoor environments with fluctuating humidity and potential hydrocarbon leaks.
The Solution: The GD2G IR is built for Zone 1 hazardous areas, detecting Propane, Butane, and other hydrocarbons. Its advanced sensor prevents condensation, eliminating false alarms caused by humidity or temperature spikes common in outdoor storage tanks and drilling rigs.
