Description:

The indoor climate hygrometer BZ15M is easy to read and understand, it indicates the ideal climate values in interior spaces depending on room temperature and season. The special scale design with colour gradient from bright to dark yellow serves to indicate both room temperature and relative humidity. 

How to assign climate values correctly
Read the room temperature from the thermohygrometer and match it with the corresponding colour ranges:
  • dark yellow for little heating 16-18 °C
  • medium-range yellow for normal heating 18-22 °C
  • bright yellow for intensive heating 22-24 °C
On the scale for the atmospheric conditions outside you can identify: 
  • winter by average temperatures below +5 °C 
  • autumn/spring by average values between 5 and 15 °C
