Indoor air quality is important for a healthy and efficient work environment. With high CO2 levels people work less efficiently, are in a more drowsy state and can experience headaches. Humidity control is also important, where low humidity can cause dry skin and high humidity can cause the growth of mold or mildew. Temperature can also affect how people work and is the most important factor in over all comfort.

This meter combines portability with accuracy to make the Portable Indoor Air Quality CO2 Meter. It has the ability to measure Carbon Dioxide (CO2), Temperature, Humidity, Dew Point and Wet Bulb. This instrument also calculates statistical 8 hour and 15 minute time weighted averages. This gives a great depiction of the air quality over an extended time period, instead of a snapshot temperature reading which could be skewed or atypical of the usual environment.

This compact meter is designed to be portable and operated with one hand. It utilizes a NDIR (non-dispersive infrared) CO2 sensor which is maintenance free and highly accurate with a resolution of 1ppm. It is great for use in schools, office buildings, greenhouses, hospitals and anywhere that large quantities of CO2 are created. The CO250 Portable Indoor Air Quality CO2 Meter User Manual is attached to this page to answer any additional questions.
