Industrial strength CO2 monitoring for any harsh environment.


The GasGuard CO2 utilizes proven infrared sensor technology for fast and accurate leak detection. With no moving parts and no cells to replace, the GasGuard CO2 provides real-time continuous monitoring and inexpensive long term operating costs. The GasGuard CO2 is carbon dioxide specific, so false alarms from floor cleaners and food off-gassing is nonexistent. The output signal is also not affected by moisture or drastic temperature variations such as washdowns, defrost cycles, etc. The GasGuard CO2 provides an industry standard linear 4/20 mA output signal compatible with most gas detection systems and PLCs. The high-quality polycarbonate or optional stainless steel enclosures offer excellent chemical corrosion protection and high impact resistance.
