Airtest TR2000 CO Lon (LonWorks®)


AirTest Electrochemical CO Transmitter – Air Quality Sensor


CO And Parking Garages Airtest TR2000-CO-Lon (LonWorks®)

Airtest TR2000-CO-Lon.  Most local codes require a very high rate of ventilation (1.5 to 2 cfm.sq ft) in enclosed parking and areas involving vehicle repair and operation. This must be provided during all hours of use. A Carbon Monoxide sensor can reduce fan energy costs by acting as an occupancy sensor for automobiles. Most codes allow fans to be intermittently operated as long as levels do not exceed 30 or 50 ppm CO (check your local code).


The TR-2000 delivers all the advantages of electrochemical sensing in a durable, long life (5 year) package that is priced to compete against less accurate MOS/Solid State sensors. The loop powered sensor delivers a linear 4-20 ma output that is easily integrated into any building control, ventilation or alarm application. The low profile design can be attached to any single gang electrical box and features a low cost replaceable sensor element.
– LonWorks® FTT-10 free topology transceiver.
– Five year life
– High accuracy sensor, +/- 5% of measurement.
– 0-200 ppm range.
– Low cost replacements sensor elements minimizes long term operating costs.
