Airtest TR2000 DIGI
AirTest Electrochemical CO Transmitter – Air Quality Sensor
CO And Parking Garages Airtest TR2000-DIGI (Replaces Airtest TR2000-CO-Lon Lonworks®) 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).ALL AIRTEST GAS SENSORS ARE PRECALIBRATED AT THE FACTORY. NO ADDITIONAL CALIBRATION IS REQUIRED.The TR-2000 Digi 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.
