concentrations from the CDH and also measures temperature
and relative humidity.
The data-logger can be easily attached to the CDH using the
provide Velcro

strip.
The data-logger can store over 7900 data points and can
sample at a user adjustable time interval.
Also provided with Boxcar software provides basic launch,

Introduction
The CDH is an easy-to-use hand-held CO
2
/Temperature
monitor.
The unit provides stable, highly accurate readings due to our
patented dual beam NDIR technology.
Equipped with a 0-4 V output, the unit is perfect for long-term
monitoring/recording.
The unit features a large, easy-to-read display with a push-
button interface which al-lows for easy calibration, quick
adjustments for altitude correction, and simple toggling
between °C and °F temperature readings.
A new feature of the sensor now includes the ability to
calculate and display the cfm/person ventilation rate in a
space based on the inside/outside CO
2
concentration.
