Overview

CPC’s CO

2

sensor (P/N 210-2000) is a non-dispersive

infrared analyzer designed for measuring

environmental CO

2

concentration in ventilation

systems and indoor spaces. Its measurement range of

0-2000 or 0-5000 ppm covers the range required to

monitor compliance with ASHRAE and other
ventilation efficiency standards.

An LCD display is available to provide local indication

of CO

2

concentration and facilitate the setup and

calibration process. An adjustable setpoint relay is

available for direct control and alarm applications.

Microprocessor-based digital electronics and a

unique self-calibration algorithm improves long-term

stability and accuracy

Mounting

Before mounting, remove the door from the circuit

board by pressing a screwdriver against the locking
tab on the top of the enclosure. Pry the circuit board





away from the mounting plate using a screwdriver
inserted into the two tab slots on the top of the

enclosure.

Choose a location for the sensor with good air

circulation, away from ventilation inlets, doors,
windows, or other points where fresh air enters the

room. The sensor should be mounted at least 4-1/2

feet above the floor. The environment temperature

must be within 32°–112°F (0°–50°C).


If wiring will be coming in through the mounting

plate from the back, punch out openings in the

mounting plate and use the plate as a template for

locating holes. Mount the mounting plate against a
wall or other flat surface by using the two mounting

holes and the screws provided (use wall anchors for

drywall installations).

NOTE: Sensors must be mounted vertically (straight

up and down) to ensure proper readings.
