For all those who look at both inner and outer qualities: the Design-Thermohygrometer BZ21M and its analogue precision measuring technology combine solidity and visual elegance with the standards of classic watch-making. Equipped with a high-quality measuring mechanism and thanks to ultimate perfection in manufacturing, as precise as a Swiss watch, the classically elegant Hair Hygrometer shows you the four important room climate parameters on its scale layout in cross-pointer design: from room temperature to relative humidity, to the display of absolute and saturation humidity.
The high-quality Thermohygrometer BZ21M combines traditional measuring technology with an easy-to-read display of the measured room climate values, which are important for your health. Optimal regulation of air humidity promotes well-being. While a humidity value that is too low can lead to health problems, mould growth can be caused if the value is too high. That is why the BZ21M allows you to permanently monitor four important indoor climate parameters to ensure a healthy and comfortable climate quality in the living room and in the office. You can record the relevant temperature and humidity values at a glance, whereby the analogue measuring device impresses with a circular stainless steel housing (Ø 130 mm), a high-quality measuring mechanism and an easy-to-read scale layout in cross-pointer design. And of course, the BZ21M does not require any batteries or maintenance inspections because it does not use any electronic parts.
Here’s how it works
Measurement of the characteristic values and regulation of the hands takes place inside the Thermohygrometer BZ21M using a bimetallic thermometer and a specially treated synthetic fibre that expands when it is moist and contracts when it is dry. The resulting change in length is converted into a rotary movement using mechanical levers and axles and transferred to the hands, similar to a clockwork movement. If necessary, the display of the low-maintenance thermohygrometer can be readjusted using an easily accessible adjustable screw. All four measured values are displayed simultaneously and in an easily comprehensible manner on the dial in the cross-pointer design:
Temperature measurement
Measuring range: 8 °C to 40 °C
Measuring accuracy: ± 2 °C
Humidity measurement
Relative humidity: 26 to 100 %
Absolute humidity: 2 to 50 g/m³
Saturation humidity: 2 bis 50 g/m³
Measuring accuracy: ± 3 % r.F.
Four of the many advantages I particularly like:
- the four climate values on one dial: room temperature, relative humidity, absolute humidity and saturation humidity
- the analogue precision measuring technology ‘’Made in Germany’’
- the special scale layout in cross-pointer design
- the easy-to-read and quick interpretation of measured values
