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.

The Desktop Indoor Air Quality CO2 monitor tests all of these factors and displays readings on a large LCD screen. With a visible and audible CO2 warning alarm with relay ouput for ventilation control. This instrument is great for monitoring offices, homes, warehouses, barns or greenhouses.
