Design thermohygrometer BZ22M

Versatile climate control and mould prevention in a timelessly elegant form

The most beautiful way to create a healthy room climate

There is no more appealing way to control indoor climate values. Whether in the commercial sector, for instance in libraries, galleries, showrooms, offices, training and meeting rooms, or in luxuriously furnished living environments – with the thermohygrometer BZ22M you always keep an eye on all important room climate data.

The BZ22M monitors as many as four values that are important for a healthy indoor climate:

  • Room temperature
  • Relative humidity
  • Dew point temperature
  • Saturation humidity

Thanks to its analogue measurement technology, the BZ22M with its cross-needle design dial and classic appearance does not need any batteries. Wherever the hair hygrometer with thermometer is used – it attracts all eyes.

Control and optimization of the heating and ventilation behaviour

The wall-mounted thermohygrometer with its high-quality appearance, enclosed in a robust stainless steel housing (Ø 130 mm), is recommended in order to permanently monitor heating and ventilation conditions. The device allows for example to detect values fallen below the dew point and related problems such as condensation and mould formation at an early stage. Similarly, temperature and humidity-sensitive indoor environments can be permanently monitored, for example to prevent corrosion in the garage or moisture damage in conservatories, guest rooms or wellness areas that are not permanently heated. This is the way to take appropriate countermeasures with targeted heating and ventilation in order to create a comfortable and healthy room climate in living rooms, bedrooms, storerooms and showrooms, offices or garages.

Precision measurement technology for the highest of demands

The thermohygrometer combines traditional measurement technology with an innovative display of the measured room climate values. The measurement data is determined and regulated inside the device by means of a bi-metal thermometer and a specially treated synthetic fibre that expands in humid conditions and contracts when it is dry. The resulting length variation is converted into a rotary motion using levers and axes and transferred to the needles in a way comparable to a clockwork.

Special scale design – displays the values and provides clarity

Thanks to its special dial design, all climate values are displayed in an easy-to-understand way and can be easily read even from a greater distance. Whereas other indoor climate measuring devices require a large number of needles and scales, the BZ22M scores with its unique cross-needle design dial.

Simple self-adjustment for permanently precise measurement results

If required, the display of the low-maintenance thermohygrometer can be readjusted by means of an integrated adjusting screw.

As many as four measured values are displayed in an easy-to-understand way on the dial in cross-needle design. This way, you create ideal conditions for keeping an optimal overview of all important climate parameters.

Temperature measurement

Measuring range: 8 °C to 40 °C
Measurement accuracy: ± 2 °C

Humidity measurement

Relative humidity: 26 to 100 %
Dew point temperature: -4 to 24 °C

Saturation humidity: 2 to 50 g/m³
Measurement accuracy: ± 3 % RH

The visually appealing thermohygrometer BZ22M is recommended for permanent indoor climate control as well as for mould and corrosion prevention.


Special equipment features of the BZ22M

BZ22M – dimensions
The true size of the compact BZ22M becomes apparent through its advantageous dimensions. With a convenient diameter of 13 cm, the dial is easy to read even from a distance. Despite having a depth of only 2.8 cm, the elegantly flat stainless steel housing simply stands out.
BZ22M – indication of the relative humidity
On the left-hand scale, the relative humidity is displayed in a measuring range from 26 to 100 %. Unwanted deviations from the desired target range become visible at one glance.
BZ22M – indication of the temperature and saturation humidity
The right-hand dual scale intelligently displays the room temperature (measuring range: 8 °C to 40 °C) and saturation humidity (measuring range: 2 to 50 g/m³) simultaneously.
BZ22M – dew point temperature
Displaying values ranging from -4 to 24 °C in precise increments of 2 degrees, the scale in the middle indicates how the measured climate parameters affect the dew point temperature of the room air.

Application examples from practical experience:

Thermohygrometer BZ22M – in the office
Too low humidity values in the office are not uncommon. With the visually appealing thermohygrometer BZ22M, you can keep an eye on the important parameters of a healthy working climate in order to counteract with controlled air humidification or dehumidification if necessary. Optimally regulated air humidity increases well-being at the workplace and reduces sick leave.
Thermohygrometer BZ22M – in the reading room
There is no more stylish way to control the humidity level in the private library. The BZ22M blends in perfectly with the ambience of your elegantly furnished reading room, so you can keep an eye on the humidity level and prevent moisture-related mould growth. A permanently regulated humidity level protects against moisture damage and contributes to the value retention of your priceless classic books.
Thermohygrometer BZ22M – in the living room
Excessive humidity in the living room is a common reason for mould growth. Prevent this health risk. The thermohygrometer BZ22M harmoniously blends into modern bedrooms and living rooms. Excessive humidity values requiring permanent dehumidification or the windows to be opened manually become visible at a glance.
