BAPI’s Nitrogen Dioxide Duct and Rough Service Sensors offer enhanced electrochemical sensing with outstanding accuracy at low concentrations. The Duct unit samples duct air using an aspiration tube. The Rough Service unit features a ventilated BAPI-Box and is ideal for parking ramps, equipment rooms and warehouses. The sensor has field selectable NO2 ranges of 0 to 2.5, 0 to 5, 0 to 7.5 and 0 to 10 ppm. It also has field selectable outputs of 0 to 5, 1 to 5, 0 to 10 and 2 to 10 VDC as well as a 3-wire 4 to 20 mA output.

Two independent SPDT alarm contacts switch at field selectable NO2 concentrations of 1.0, 2.5, 5.0, 7.5 and 10.0 ppm. An alarm timer holds the output relays on for a fixed time after the NO2 level has fallen below 80% of setpoint.  This allows additional fan run time to be sure that the NO2 has been purged.

Sensor elements last approximately 7 years and the sensor module is field replaceable. The sensor element is self tested daily for proper operation.
