The Detcon Sensor Duct Mount Kit allows a Detcon gas sensor assembly to be mounted so that its sensor is located inside of an air duct, while its transmitter, located outside the duct, is still accessible for calibration and other adjustments. 

This method of installation is much more economical than the typical sample draw type system that is normally used in such applications. 

In operation, air flow through the duct enters the duct mount chamber through ports facing the oncoming flow of air. 

Once inside the chamber the sample passes by the sensor and then exits through similar ports that face the opposite direction. 

If any target gas is present in the chamber, the sensor output signals and/or alarm functions, will respond accordingly.
