BAPI's Carbon Monoxide Rough Service sensor offers enhanced electrochemical sensing with outstanding accuracy at low concentrations. It features a ventilated BAPI-Box and is ideal for parking ramps, equipment rooms, and warehouses.   The sensor has a CO range of 0 to 500 ppm with field-selectable outputs of 0 to 5, 1 to 5, 0 to 10, and 2 to 10 VDC. It includes optional humidity measurement with one of the above voltage outputs and temperature via a 10K-2, 10K-3, or 20K thermistor. The CO, temperature, and humidity outputs are also available via BACnet MS/TP. The field-replaceable sensor element lasts approximately seven years and is self-tested daily.
