TempPro TP260B Wireless Indoor Outdoor Thermometer Hygrometer

Best For:

For the homeowner who wants the most accurate indoor/outdoor readings available: Swiss-made Sensirion sensors deliver ±0.5°F accuracy, the tightest in the lineup. Like wine cellar, nursery, greenhouse, or storage room, you know the exact conditions, not just an approximation.

For anyone monitoring across a large property or through multiple walls: 1000ft wireless range is double the lineup standard. The signal stays strong through floors, walls, and obstacles, making it reliable for large homes, garages, and outbuildings well beyond the yard.

For the detail-oriented homeowner who tracks trends, not just snapshots: Backlit display, front-touch buttons, and trend arrows show whether conditions are rising or falling. Max/min records let you see what happened overnight or while you were away.

Not Ideal For:

Those who want a larger, easier-to-read display: For a 4-inch touchscreen readable from across the room, the TP65B offers the largest display in the lineup.
