The Major Tech MT91 mini hygrometer measures relative humidity, temperature, and dew point while the modern ergonomic design with a large backlit dual display makes it easy to use in any application. Relative humidity is normally expressed as a percentage, a higher percentage means the air-water is more humid. At 100% humidity, the air is saturated and at dew point.
The Bluetooth connectivity allows users to transfer and share measured data to a smartphone and the app is available on both Android and IOS platforms. Other features include Min/Max record more and data hold.
