GG-R438A-500 CTI Gas Sensor, R438A 0-500 PPM, 4/20 mA Output, Temperature Controlled Polycarbonate

The GG-R utilizes proven infrared sensor technology for fast and accurate leak detection. With no moving parts and no cells to replace, the GG-R provides real-time continuous monitoring and inexpensive long-term operating costs.

The GG-R is refrigerant gas specific, so false alarms from floor cleaners and food off-gassing is nonexistent. The output signal is not affected by EMI/ RFI, or moisture. R11, R22, R134, R507, R401, R402, R404, R407, R410, R448, R422D are a few common refrigerants the GG-R sensor can detect.

The GG-R provides an industry standard linear 4/20 mA output signal compatible with most gas detection systems and PLCs. The high-quality polycarbonate enclosure offer excellent chemical corrosion protection and high impact resistance.
