The Meross MS120 hygrometer and thermometer measures temperature, relative and absolute humidity, dew point, and vapor pressure deficit (VPD). Its 1.9-inch LCD displays the readings and lets you switch between five parameters, with values updated every 3 seconds. Bluetooth Low Energy (BLE) connectivity lets you view graphs and measurement history in the Meross app.
Adjustable audible alarms and app notifications alert you when the set temperature or humidity limits are exceeded. The housing is rated IP65 for dust and water protection and is resistant to UV radiation. The device is suitable for indoor and outdoor use. It can be used in greenhouses, terrariums, wine cellars, and storage rooms, as well as to monitor storage conditions for musical instruments or cigars.
