Amprobe CO2-200 CO2-Meter - Manual (Page 9)

INTRODUCTION
Thank you for purchasing this CO2 meter. It measures
CO2 level, air temp., dew point, wet bulb temp. and
humidity and is an ideal instrument for indoor air quality
(IAQ) diagnosis.
Poor indoor air quality is considered unhealthy because
it causes tiredness, loss of ability to concentrate, and
even illness (ex. Sick Building Syndrome). IAQ monitoring
and survey, especially on CO2 level and air ventilation
become widely applied in public areas such as offices,
classrooms, factories, hospitals and hotels. It is also
suggested in regulations of industrial hygiene in some
countries. (Appendix)
With NDIR (non-dispersive infrared) sensor used, this
CO2 meter is stable in long term monitoring. And the
built-in relay for alarm output is especially useful in
ventilation control and HVAC system performance
verification.
