CD2 Series Air Quality Sensors are duct mount all-in-one sensors for monitoring air quality. The CD2 series device combines CO2, temperature, humidity, VOC and particulate matter (PM) sensing into a single unit to ensure a building’s optimum air quality and energy efficiency. Each CD2LAXAVP device is an active sensor that converts a measurement into the following Analog output options: 4-20 mA, 0 to 5 Vdc or 0 to 10 Vdc
- Analog output: 4-20 mA, 0 to 5 Vdc or 0 to 10 Vdc
- LCD Positive Display with Backlight
- Measurement Type: CO2/VOC/Particulate Matter/Temperature
- Easy to Maintain: Self Calibrating
- Easy to install: Latch on sensor cover and screwless terminal block wiring with spring actuator
- Different models are available based on application requirements for lower-cost installations.
