Information about the device
Device description
The dew point scanner BP25 uses an infrared and humidity
sensor to measure surface temperatures as well as air
temperature and humidity without contact. An integrated dual
laser serves for the determination of the measuring spot
diameter.
The dew point is detected from these values. If the temperature
in one part of the room is at or below the dew point, then the
humidity in the air condenses. This can cause mould to form.
Using the dew point scanner BP25 to measure the dew point,
you can accurately pinpoint areas at risk of mould formation or
poor insulation.
The risk of condensation forming at the measuring spot is
indicated both by an acoustic alarm function and a changed
display colour.
When not in use, an automatic switch-off saves the battery.
Measuring principle
The device measures the temperature by means of an infrared
sensor. Important factors playing a role in the temperature
measurement are the measuring spot diameter and the
emissivity of the surface to be measured, which is set to the
fixed value of 0.95 here.
Measuring spot
Observe the ratio of the distance to the measuring spot
diameter. The larger the distance to the object, the larger the
measuring spot diameter and hence, the less precise the
measured result. The on-demand dual laser indicates the
approximate diameter of the measuring spot, which is used by
the device to calculate an average temperature. Consequently, it
is a mere aiming aid and not intended for the actual
temperature measurement. The smaller the measuring spot, the
more precise is the measured result.

Operation
Inserting the battery
Note
Make sure that the surface of the device is dry and the
device is switched off.
22
21
1. Open the battery compartment by folding open the
cover(21) with your fingers.
2. Use the battery clip(22) to connect the new battery with
correct polarity.
3. Insert the battery in the battery compartment.
4. Close the cover of the battery compartment.
Carrying out a measurement
Info
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.
• Ensure that the surface to be measured is free of dust, dirt
or similar substances.
• To be able to gain exact measurement results on surfaces
which reflect heavily, stick matt masking tape to the
surface or apply matt black paint with a very high and
known degree of emission.
• Note the 20:1 ratio of the distance to the measuring spot
size. The larger the distance to the object, the larger the
measuring spot diameter and hence, the less precise the
measured result.
1. Point the device at the object to be measured.
2. Press the measurement button(3).
ðThe device switches on.
ðThe temperature of the measured object is shown on
the measurement value display for temperature at the
measuring spot(16). Depending on the settings, either
the ambient temperature, the relative humidity or the
dew point temperature are additionally displayed in the
measurement value display(18).
You can determine the risk of condensation forming at the
measuring spot by reading the scale(15) on the display(8), or
based on the colour of the display illumination. Depending on
the risk of condensation forming at the measuring spot, the
display is illuminated in one of the following colours:
Display colour Meaning
green Surface temperature in normal range
orange Surface temperature near dew point
(borderline). When the alarm is enabled, a
repetitive alarm tone is emitted.
red Temperature of measured surface at or
below dew point.
ATTENTION: Risk of condensation forming!
When the alarm is enabled, a constant
alarm tone is emitted.
