1. Introduction
This meter can measure the CO
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 CO
areas such as offices, classrooms, factories, hospitals and hotels. It is also suggested in regulations of
industrial hygiene in some countries.
With NDIR (non-dispersive infrared) sensor used, this CO
the built-in alarm output is especially helpful in ventilation control and HVAC system performance
verification.
