Long-Life CO Monitoring for Parking & Vehicle Maintenance Facilities
The Teren CMW22 is a high-performance wall-mount Carbon Monoxide (CO) transmitter designed specifically to control ventilation in car parks, vehicle maintenance workshops, and engine test rooms. By accurately measuring CO levels, it enables Demand Controlled Ventilation (DCV) strategies—ensuring safety compliance while significantly reducing energy costs by running fans only when necessary.
This specific model, the CMW22, is configured with a 4...20 mA output and a wide detection range of 0...400 ppm, making it the industrial standard choice for most vehicle exhaust monitoring applications.
Key Features & Benefits
-
Superior Sensor Longevity: Unlike standard sensors that last only 1-3 years, the CMW22 utilizes an advanced electrochemical sensor with a 7 to 10-year life span. This durability protects your long-term investment and reduces replacement frequency.
-
Minimal Maintenance Required: Designed for stability, this unit outperforms competitors that require calibration every 6-12 months. The CMW22 maintains 5% accuracy with recalibration intervals as long as 3 to 5 years, drastically lowering maintenance costs.
-
Energy-Efficient Operation: Perfectly suited for DCV systems, it helps buildings meet HVAC regulations for enclosed vehicle areas without wasting energy on constant ventilation.
-
Robust & Reliable: Features digital circuit technology with built-in protection against over-voltage and reverse polarity. The housing is rated IP33 and includes an LED status indicator for easy visual verification of operation.
-
High Interference Immunity: Engineered to resist signal interference, ensuring stable and reliable readings in electrically noisy industrial environments.
