Wall-mounted CO2 Sensor - CWE

1. Wall-mounted CO2 Sensor CWEDescription:

The CWE, as a non-dispersive infrared analyzer, is designed to measure CO2 concentration in ventilation systems and indoor living spaces. Its 0-2000ppm measurement range complies with ASHRAE and other ventilation control standards. The CWE series offers users the versatility of optional 4-20mA or 0-10VDC outputs. Microprocessor-based digital electronics and a proprietary self-calibration algorithm enhance long-term stability and accuracy.

2. Applications of Wall-mounted CO2 Sensor CWE:

Ventilation control based on space occupancy

Facilitates compliance with ASHRAE 62.1-2004 air quality standards

Office buildings, conference rooms, schools, retail stores, etc.

Microprocessor design improves accuracy and reduces installation time

Non-dispersive infrared (NDIR) technology with repeatability of ±20 ppm ±1% of reading

Innovative self-calibration algorithm... easy maintenance

5-year calibration interval (recommended)

Low environmental sensitivity

Alarm relay setpoint for direct ventilation control
