CO2 monitor for indoor air quality measurement
CO2 Display
measures CO2, rh & temperature
internal logger with USB access
easy to read display
Improve health and safety and workplace environments.
This display unit is a useful aid to improving workplace conditions. CO2 levels can increase in work areas and closed rooms. Meeting rooms and training rooms are often internal rooms that may not have the best ventilation systems. High CO2 can lead to loss of concentration and fatigue. A wall mounted display can indicate that ventilation needs to be improved.

This low cost CO2 display can be desk, bench-top or wall-mounted and provides useful information. It can also be mounted in cellars and areas where CO2 could accumulate.
The display acts as a visual warning when levels increase and the internal logger records the date, time, CO2, rh and temperature for download to a PC for charts and analysis if necessary.
