The CDH hand held monitors feature patented
absorption infrared technology.
Accurately measures CO2 and Temperature while calculating real-time
The CDH Series also offers data logging and RH data gathering
capabilities when purchased with available accessories.
Product kits include a power adapter, however, the unit may be
operated up to 80 hours on 4 AA batteries (not included).
Equipped with CDH patented dual beam Absorption Infrared technology,
the CDH Series product line is comprised of easy-to use CO2/temperature
monitors designed for use in residential or commercial applications.
The CDH series offers the capability to display CO2 readings and
calculate outside air ventilation rates in cfm/person.
The handhelds are an ideal tool for: identifying energy saving
opportunities in over-ventilated spaces, determining if air quality
complaints are due to insufficient ventilation, or locating the
presence of combustion fumes generated from vehicles and
If you wish to record CO2 concentration for
further analysis, we offer CO2 View software that allows you to log
concentrations directly to a PC.
For remote monitoring, we offer a Datalogging Kit that easily
attaches to the back of the CDH.
