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.

Why The TR-2000?

• Electrochemical performance at a MOS (solid state)price. One-half to two-thirds the cost of comparable electrochemical sensors.
• Two-wire, loop powered for easy integration with EMS & DDC Systems.
• Five year life vs 18 months for most other electrochemical sensors.
• High accuracy sensor, +/- 5% of measurement.
• Linear output over complete 0-200 ppm range.Custom ranges available.
• Low profile, attractive enclosure that can be mounted in any single gang J box.
• Low cost replacements sensor elements minimizes long term operating costs.

AirTest Electrochemical Vs MOS/Solid State

• Higher accuracy in the 0-50 ppm range means more energy savings for ventilation control in vehicle operation and parking areas.
• No temperature or humidity interference eliminates seasonal drift of sensors.
• Much less sensitive to other gases and less likely to be poisoned.
• Significantly less long term drift means less maintenance.
• Consistent linear output between sensors means specialized operational curves and control points are not necessary.
