Extech 445703 Big Digit Hygro-Thermometer
The Extech 445703 is a large-digit, dual-display hygrometer/thermometer that simultaneously shows humidity and temperature. It features 1-inch LCD digits, max/min memory with reset, a °C/°F selector, and mounting flexibility (with a tilt stand and wall mount). It’s suitable for environments where readability and tracking extremes matter.
Description
The 445703 is built for clarity and convenience in monitoring ambient conditions. Its oversized 1″ digits on a spacious dual LCD panel allow users to see both relative humidity and air temperature at a glance without switching screens. Behind the scenes, the instrument tracks maximum and minimum values, which can be reset manually. The temperature scale is user-selectable between Celsius and Fahrenheit. It covers a typical indoor range, with humidity from about 10 % RH upward and temperature from –10 °C to 60 °C (14 °F to 140 °F). A low battery indicator appears when the power is low. For installation, it includes a fold-out tilt stand and a wall mounting bracket, making it useful for both tabletop and wall placements. It runs on a single AAA battery and is relatively lightweight for its size.
