• Explosion-proof enclosure for classified areas
• Carbon Monoxide specific electrochemical sensor technology
• 0-200 ppm factory range
• Electronics potted to eliminate internal corrosion
• Industry standard 24VDC, linear 4-20 mA output
• Operating temperature from -4°F to +122°F
• Accurately monitor CO levels for important action levels
• No false alarms from interference gases
• Real-time continuous monitoring for early CO detection

The GG-CO-EXP is designed for detection of carbon monoxide vapors in hazardous areas. The standard detection range of 0-200 ppm provides real-time continuous monitoring of concentrations accurately down to 20 ppm with no false alarms.

The GG-CO-EXP utilizes a proven hydrogen sulfide specifc electrochemical sensor for detecting poisonous CO gas concentrations. No false alarms due to cross-sensitivities from other gases, and no false alarms from temperature or humidity fluctuations.

The GG-CO-EXP provides an industry standard linear 4/20 mA output signal proportional to ppm concentration of carbon monoxide. Long sensor life with minimal span adjustment can be expected in most applications. The sensor is designed for simple calibration and the sensor head is easily field replaceable.

Carbon monoxide gas is approximately the same weight as air and will mix evenly with the air in all spaces. For personnel protection, mount the sensor at a height in the breathing zone of the employees. It would typically be 4 to 5 feet off the ground, which also allows easy access. As a general rule of thumb, try to mount sensors within 30 feet of potential CO sources.

The GG-CO-EXP is intended for horn/ strobe and ventilation activation, and is also useful for alarm outputs such as phone dialers and other alarm functions.

Typical sensor element life is 5+ years, with only a 20:1 cross-sensitivity to hydrogen. Field replaceable sensor element keeps long term mainte- nance simple and low cost. Every circuit board is potted to completely eliminate corrosion to the electronic components and copper tracing on the circuit board. An explosion-proof aluminum enclosure houses the transmitter.
