The Beurer HM 22 Thermo Hygrometer and Timer is a compact room monitor that keeps an eye on the indoor environment at a glance. It displays the room temperature, relative humidity, date and time on a single large screen, and adds a built-in timer — so one small device covers a few everyday jobs whether it's in the nursery, kitchen, at home or in the office.
If you like to keep track of how warm and how humid a room feels — something many parents pay closer attention to in a baby's room — the HM 22 gives you a clear, easy-to-read reading without any fuss. It can stand upright on a shelf or surface using the fold-out stand, or be mounted on a wall with the built-in hook, so you can position it wherever the display is easiest to see.
What it measures
The HM 22 shows the room temperature across a measurement range of 10°C to 50°C (14°F to 122°F), with an accuracy of ±1°C between 0°C and +40°C, and ±2°C at the outer ends of the range. Relative humidity is measured from 20% to 95%, accurate to ±5% RH between 40% and 80%. You can switch the temperature display between Celsius and Fahrenheit (°C/°F) to suit how you prefer to read it.
Timer and display
The integrated timer is adjustable via sensor buttons and sounds an acoustic signal when the time is up — handy for anything from timing a routine to a task in the kitchen. Everything sits on a large, easy-to-read display, so the information you want is visible at a glance.
Placement and power
At roughly 135 g and 110 x 105 x 29.5 mm, the HM 22 is small enough to tuck onto a shelf or mount flat against a wall. It runs on 2x 1.5 V AAA (LR03) batteries and is backed by a 3-year limited warranty.

The Beurer HM 22 Thermo Hygrometer and Timer is a great option for parents who:
- Want to keep track of room temperature and humidity in a single, easy-to-read display
- Prefer the flexibility of either standing the device on a surface or mounting it on a wall
- Would find a built-in timer with an audible signal useful around the home

Pandylane Pro Tip
Pandylane Pro Tip: If you're using the HM 22 to keep an eye on a room's climate, mount it or place it at roughly the same height as the space you care about most — readings can differ between floor level and shelf height.
