The CDR CO2 Sensors are ideally suited for
Demand Controlled Ventilation(DCV) in buildings.
The CDR series sensor measures CO2 concentrations and can be
utilized as an indicator of occupancy.
This approach drives a ventilation control strategy based on actual
occupancy while maintaining ASHRAE recommended per-person
Over-ventilation can be reduced, energy can be saved, and air
quality can be optimized by including the CDR CO2 Sensor in your
The wall-mounted CDR series sensors are low profile, unobtrusive,
and designed for installation in any office space or conference room.
The CDR transmitter includes a dual analog output (0-10V and
4-20mA), a mounting/wiring sub-base, and a Lifetime Calibration
All CDR Series sensors offer a SPDT relay (normally open or closed)
and can be custom programmed to a specific measurement and output
range using the UIP software interface or on-board keypad (display
Patented Absorption Infrared/Gas

Mounting bracket with terminal block provides quick, easy wiring.
Gas permeable, water resistant diffusion filter prevents particulate and water
contamination of the sensor.
Locking screw secures cover and sensor to the mounting bracket for tamper resistance.
Dual simultaneous analog output (V &

The CDG is complete with a CDR 142 and designed to protect the
sensor in damp or wet environments as might occur in agricultural,
industrial or food processing instruments.
The CDG is ideal for monotoring CO2 as a suurogate for combustion
fumes in parking garages, tunnels and loading docks.
The enclosure is designed to protect the sensor from dripping or
The transparent cover allows viewingof the senso/display.
Four diffusion ports allow for entry of CO2.
Knockouts are provided for conduit connection.
Response time of the sensor is slowed to approximately 30 minutes to
measure a 90% step change in concentrations.
The CDG is designed to screw directly to a wall.
