Precision monitoring for indoor spaces

The TIMETEK DM9442 measures temperature from 14°F to 122°F with ±0.5°F accuracy and humidity from 0% to 99% RH with ±5% precision. A 3.2-inch round LCD refreshes every 30 seconds and shows a rolling 24-hour high and low history for both readings. The green brushed stainless frame suits living rooms, nurseries, offices or wine cellars.

Upgrade from basic analog dials

This unit replaces single-function thermometers or hygrometers that lack memory and comfort indicators. The jump is worth it when you need simultaneous temperature and humidity tracking, a visual Dry/Comfort/Wet gauge and a true rolling 24-hour record instead of a midnight reset. It also adds Celsius/Fahrenheit switching and a wall-mount option.

Standalone operation limits

The monitor runs on two AAA batteries (not included) with alkaline chemistry and requires no Wi-Fi, Bluetooth or app pairing. Data stays on the device and cannot be exported, logged remotely or integrated with smart-home systems. Battery life varies with usage and the 30-second refresh interval is fixed.

Questions about this item

What size opening does the 3.2-inch round display need on a wall?

The unit measures 2.4 inches wide by 3.96 inches tall by 1.3 inches deep and weighs .33 pounds; the integrated wall mount fits a single screw or nail.

How do I set it up and what step do people miss?

Insert 2 AAA alkaline batteries, choose °F or °C, then place it on a desk or hang it via the built-in wall mount; the step often missed is waiting for the first 30-second refresh before trusting the reading.

What will I need to replace later?

The device runs on 2 AAA alkaline batteries; when the display dims or updates stop, replace both cells at the same time.
