The Beurer HM-16 Thermo Hygrometer is a compact indoor climate monitor that keeps you informed about the temperature and humidity in your home or office at a glance. Rather than just showing raw numbers, it uses simple face icons to tell you instantly whether the air in the room is comfortable, too dry, or too humid — useful for anyone trying to maintain a healthier indoor environment or protect furniture, instruments, or sensitive equipment from poor humidity conditions.
It can stand on a shelf or desk using its fold-out stand, or be mounted on a wall using the built-in hook, so it fits into almost any room. The display also tracks maximum and minimum temperature and humidity readings, and switches between °C and °F at the press of a button, making it a simple, no-fuss way to stay on top of your indoor climate.

Frequently Asked Questions
What do the face icons on the display mean?
The smiling face appears when the room is at 20–25°C with 30–60% relative humidity, which Beurer considers an ideal indoor climate. A neutral or dry-face icon appears at any temperature when humidity drops below 30%, indicating the air is too dry, while a sad or humid-face icon appears at any temperature when humidity rises above 60%, indicating the air is too humid.
How long does it take to get an accurate reading?
In a changing environment — for example, after moving the device to a new room — it needs approximately 15 minutes to stabilise and deliver a reliable temperature and humidity reading.
Can I mount this on a wall instead of standing it on a surface?
Yes, the HM-16 has both a fold-out stand for tabletop placement and a hook on the back for wall mounting, so you can choose whichever suits the room.
How do I clear the recorded maximum and minimum values?
The maximum and minimum recorded temperature and humidity clear automatically every 24 hours. If you want to reset them manually at any time, simply remove the battery and reinsert it.
What’s the measurement range and accuracy of the HM-16?
It measures temperature from 0°C to +50°C, accurate to within ±1°C between 0–40°C and ±2°C between 40–50°C. Humidity is measured from 20% to 95% RH, accurate to within ±5% between 40–80% RH and ±8% at the outer ends of the range (20–40% and 80–95% RH).
