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 features the ability to test and record all of these parameters up to 20,000 sets of data. This makes it extremely useful for monitoring areas such as schools, hospitals, greenhouses, residential houses, warehouses, offices and anywhere else that large amounts of CO2 are created.

This recorded information can then be downloaded to a PC with the included Windows compatible software which analyzes and organizes data. The sensor is attached to the meter by a coiled cable making it easy to check air inside of ducts, vents, crawl spaces or any other hard to reach area.
