About Indoor & Outdoor Temperature / Humidity Monitors
Measure temperature and humidity in the home, the office, your greenhouse, the lab, and anywhere else with these instruments. You will be able to see if there are cold or warm areas and make adjustments to your heating or cooling system.
Humidity monitors measure, and report the relative humidity (RH) of air or determine the amount of water vapor present in the gas mixture (air) or pure gas.
