CO2 Wall w/ RH
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 (NDIR) repeatable to ±20 ppm ±1% of measured value
- Innovative self-calibration algorithm...easy to maintain
- 5-year calibration interval (recommended)
- Low ambient sensitivity
- Field-selectable outputs for operation flexibility
Revolutionary direct duct mounting design
- Integrated transducer and probe...eliminates the need to install a separate pick-up tube
- Snap-on faceplate...no screws required, making installation and service a snap
- Adjustable duct probe...simplifies installation and airflow monitoring
- CO2, humidity, and temperature sensing all in one compact device...fewer units to buy and install
