Clear LCD Display with 18° Elevation Angle

This digital hygrometer and thermometer combines temperature and humidity monitoring in a compact black unit. A built-in 18° elevation angle and a sharper 2.4 inch LCD screen allow readings to be seen clearly at a glance. It is suited for bedrooms, baby rooms, greenhouses, incubators and reptile terrariums. The pocket-sized cuboid design makes it easy to move between locations or take on trips.

Temperature Range 15 to 122

The sensor measures temperature from 15 to 122 with an error of ±2 and humidity from 10% to 99% RH with an error of 5% RH. Readings refresh every 2.5 seconds, so rapid environmental changes are reported quickly. The specified ranges limit use in conditions colder than 15 or hotter than 122. Extremely dry or saturated environments outside 10–99% RH cannot be measured accurately.

Up to 36 Months Battery Life on One AAA Alkaline

A single AAA alkaline battery (not included) powers the unit for up to 36 months, far longer than button-cell alternatives. The monitor is ready to use once the battery is inserted; no wiring or external supply is needed. Buyers who want continuous logging, wireless alerts or multi-room monitoring will need a different class of device.
