MEROSS MS120 Intelligent multifunctional hygrometer and thermometer
Description
About this product
The intelligent multifunctional Meross MS120 hygrometer and thermometer measures temperature, relative and absolute humidity, dew point and vapor pressure deficit (VPD). You read the results on a 1.9-inch LCD display, and review measurement history in the Meross app via Bluetooth Low Energy.
Accurate temperature and humidity measurements
The sensor measures temperature with an accuracy of ±0.2°C and humidity with an accuracy of ±2% RH. Measurements are taken every 3 seconds, so changes in conditions are visible almost immediately. On the LCD display you switch between five parameters when you need a specific value.
Alarm and history in the app
The built-in audible alarm will signal when set values are exceeded, and its volume reaches 100 dB. Notifications also arrive in the app, so you don't have to stand next to the device. Locally stored data covers 120 days, and the app shows charts and lets you export them.
Enclosure for outdoor use
The enclosure is dust- and waterproof to IP65 and resistant to UV radiation, so the device is also suitable for outdoor use. The hygrometer operates at temperatures from -20°C to 60°C, and at humidity from 10% to 90% without condensation. This lets you monitor places exposed to dust, moisture and variable temperatures.
Replaceable CR123A battery
The hygrometer is powered by one replaceable CR123A battery. The battery lasts up to 3 years of operation. When it is used up, you replace it without having to replace the entire device.
