Three-unit monitoring set

The TempPro TP49 pack supplies three identical hygrometer thermometers for simultaneous room monitoring. Each unit measures temperature from -58°F to 158°F and humidity from 10% to 99%RH with selectable °F or °C readout. The bundle suits households that want consistent climate data across nursery, greenhouse, humidor or guitar room without buying separate devices.

Included batteries and mounting hardware

Three AAA 1.5V batteries are supplied so every gauge works straight from the box. A printed user manual covers basic setup and comfort-icon interpretation. Each unit offers a fold-out tabletop stand, a magnetic back for ferrous surfaces and a hanging slot for wall or peg mounting, giving flexible placement on shelves, fridge doors or greenhouse frames.

Accuracy and refresh limits

Temperature reads within ±1°F or ±1°C and humidity within ±2% to 3%RH, so small drifts near comfort thresholds are expected. The display updates every 10 seconds, which is adequate for gradual room changes but too slow for tracking rapid fluctuations from HVAC cycles or door openings. Operating and storage ranges both span -58°F to 158°F, so the units tolerate the same extremes they measure.

Questions about this item

How often will the AAA batteries in each TP49 unit need replacing?

Each gauge runs on one 1.5 V AAA alkaline cell; with a 10-second refresh rate and no backlight, typical life is many months before a swap is needed.

What measurement limit will the TP49 hit first in a very hot or very cold room?

The temperature range stops at 158 °F (70 °C) on the high side and -58 °F (-50 °C) on the low side; humidity reads 10 % to 99 % RH.

Does the TP49 produce any audible noise or noticeable warmth while running all day?

The unit has no fan, speaker or backlight, so it stays silent and does not generate perceptible heat during continuous operation.
