BZ05 Indoor Thermohygrometer

Indoor climate station with feel-good indication

An optimum indoor climate is the fundamental prerequisite for the health and wellbeing of residents. The two decisive factors for "feel-good surroundings" – room temperature and relative humidity – are indicated in large digits by the BZ05 on the clearly legible LCD display along with time or date. Furthermore, recorded minimum and maximum values can be recalled at the BZ05.

Also convenient is the integrated feel-good indication: An indicator easily understandable shows, whether the room climate values range in a corridor optimal, acceptable or critical for human beings.

The timelessly elegant design, optional table installation or wall mounting and integrated alarm function make the BZ05 a multi-functional thermohygrometer for more than just living and bedrooms, workspaces, conservatories or basement hobby rooms.

A few practical benefits:

  • Simultaneous display of room temperature, humidity and time or date
  • Additional feel-good indication
  • Display of recorded minimum and maximum values
  • Large display with easily legible measurement value display
  • Alarm function
  • Free standing or wall mounted
  • Optimum price-performance-ratio
