Poor air quality may cause tiredness, inability to
concentrate, and even illness (i.e., Sick Building
Syndrome). This instrument is ideal for monitoring indoor air
quality in crowded public spaces with potentially high levels
of CO
2
(carbon dioxide) such as offices, factories,
classrooms, hospitals and hotels. The same measurement
parameters can also be used to test air from HVAC
equipment.
Simultaneously backlit display of CO
2
(carbon dioxide)
level, humidity and air temperature, or the user may choose
a rotating display of dew point and wet bulb temperature
instead of air temperature. Also calculates TWA (Time
Weighted Average) and STEL (Short-Term Exposure Limit).
Simple user calibration of CO
2
and RH. Features audible
C0

threshold alarms, min/max/ave, hold and a USB
computer interface. NDIR (non-dispersive infrared)
technology ensures long-term accuracy, stability and
reliability.
