Gas Sensors

A broad range of individual 4-electrode gas sensors. The sensors are suitable for use in fixed installation sensing heads, portable safety instruments, urban/indoor air monitoring and stack gas analyzers. CO2 infrared sensors are supplied in the standard miniature (20mm diameter) gas sensor housing. An internal temperature sensor is included to enable the temperature to be monitored, providing compensation for temperature effects, including ideal gas law corrections.
