Humidity Meters

Easily measure relative humidity (or the percentage of water vapor present in the air or in a gas) and calculate dew point and ice point with ThermoWorks hygrometers, humidity meters and data loggers. Ensure the quality of perishable goods in transportation and storage for food processing and HACCP compliance. Perfect for pharmaceutical applications, computer rooms, construction, horticulture and heating and ventilation (HVAC). Also great for humidors, guitar and violin cases, or gun safes.
