Information about the device
Device description
The thermohygrometer BC21 can be used to determine the air,
dew point and wet-bulb temperature as well as the humidity
level of indoor areas.
For assessing the measurements, a Max/ Minfunction
(maximum and minimum value) and a Holdfunction for freezing
the currently measured value are also available.
When not in use, an automatic switch-off saves the battery.

ðThe display is switched on.
ðThe device is ready for operation.
2. Point the device at the area to be measured.
ðWait for a moment to achieve a stable measured value.
Note:
Note that moving from a cold area to a warm area can lead to
condensation forming on the device's circuit board. This
physical and unavoidable effect can falsify the measurement. In
this case, the display shows either no measured values or they
are incorrect. Wait a few minutes until the device has become
adjusted to the changed conditions before carrying out a
measurement.

ðMAX(9) appears on the display.
ðActuating the MAX/ MINbutton(7) starts a new
measurement. The value now appearing on the display
is the reference value.
ðMAXfunction: The maximum value of the newly started
measurement interval is displayed. Values smaller than
the one displayed will not be indicated.
2. Press the MAX/ MINbutton(7) again.
ðMIN(10) appears on the display.
ðActuating the MAX/ MINbutton(7) starts a new
