Two-Pack Indoor Climate Monitor

This 2-pack of mini digital hygrometer thermometers suits homeowners and hobbyists who need simultaneous temperature and humidity readings in several small spaces such as mason jars, reptile tanks or instrument cases. Each unit fits on a tabletop or shelf and ships ready to use.

Included LR44 Cells Remove First Power Step

Two LR44 button cells come pre-installed in every meter so the LCD display activates immediately. The supplier notes that a loose cell during transit can leave the screen dark; reseating the battery restores operation without extra tools.

±2°F Temperature Accuracy Decides Suitability

The sensor delivers temperature readings within ±2°F across a -58°F to 158°F range and humidity within ±5% RH from 10% to 99% RH, refreshing every 10 seconds. Buyers who need tighter tolerances for laboratory or calibration work should look elsewhere.

Questions about this item

How often do the LR44 batteries need replacing?

The unit runs up to 8 months on the two included LR44 cells before a fresh pair is needed.

What is the widest humidity range the sensor can report?

It reads from 10 % to 99 % RH, so anything outside that span will not register.

Does the LCD stay cool and silent during continuous operation?

The device has no fan or moving parts, so it runs silently and generates no noticeable heat.
