The CWE are non-dispersive infrared (NDIR) analyzers designed for measuring environmental CO2 concentration in ventilation systems and indoor living spaces. Their measurement range of 0-2000ppm makes them compliant with ASHRAE and other standards for ventilation control. The CWE Series provides a user-selectable 4-20mA or 0-10VDC output for versatility. Microprocessor-based digital electronics and a unique self-calibration algorithm improves long-term stability and accuracy. 

APPLICATIONS

• Controlling ventilation in response to occupancy
• Facilitating compliance with ASHRAE 62.1-2004 standard for air quality
• Office buildings, conference rooms, schools, retail stores, etc.

Microprocessor design increases accuracy and reduces installation time

• Non-dispersive infrared technology repeatable to ±20 ppm ±1% of measured value
• Innovative self-calibration algorithm...easy to maintain
• 5-year calibration interval (recommended)
• Low ambient sensitivity
• Alarm relay with setpoint for direct ventilation control
• Output 4-20mA/0-10V for flexible control system interface
• 3-year factory warranty from date of purchase
