Extech 401014 Big Digit Indoor/Outdoor Thermometer

This model is designed for everyday monitoring of ambient conditions both inside and outside your space. The built‑in sensor handles the indoor temperature range, while an external, weather‑resistant probe (with about 9.6 ft/3 m of thin cable) measures outdoor (or remote) conditions, allowing you to keep the display unit indoors while the probe sits outside or in another zone. The large digits (about 1″ or 25 mm high) ensure easy readability from a distance. It stores minimum and maximum values so you can track extremes over time. Switchable between °C and °F, the unit is easy to mount on a wall or place on a desk via its built‑in stand and bracket. It is powered by a single AAA battery and comes with everything needed for setup (probe, stand, mounting bracket). Its combination of simplicity, large display and dual‑sensor capability makes it well‑suited for homes, offices, greenhouses, storage areas, and general temperature‑monitoring tasks.
