Veris Industries CD2 Series Duct Mount All In One RH Temp VOC and PM
Sensing Owner’s Manual
CD2 SERIES
Duct Mount All-in-One CO2 , RH, Temp, VOC and PM Sensing
CD2 Series Air Quality Sensors are duct mount all-in-one sensors for monitoring air quality. The 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 device is an active sensor that converts a measurement into one of the following output options:
- Analog output: 4-20 mA, 0 to 5 Vdc or 0 to 10 Vdc
- Protocol output : BACnet MS/TP, Modbus RTU
Different models are available based on application requirements for lower- cost installations.
CD2 is available with an LCD display option on selected models. See Ordering Information for details
BACnet & Modbus
Embedded BACnet and Modbus communication protocols for easy systems integration
Self-calibrating
Innovative self-calibration algorithm…easy to maintain
Dual-beam NDIR CO2 sensor
Dual-beam, non-dispersive infrared technology (NDIR) repeatable to ±20 ppm ±1% of measured value… high accuracy measurement
APPLICATIONS
- HVAC systems
- Indoor air quality monitoring
- Life sciences applications
Easy to install
Latch-on sensor cover and screwless terminal block wiring with spring actuator
Field selectable
Field-selectable outputs for operation flexibility
Field replaceable
Replace RH element and temp transmitter in the field… maintain accuracy and minimize downtime and cost
- Key component for the LEED green building program and WELL Building Standard*
