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.

Transport and storage

Note
If you store or transport the device improperly, the device may be damaged.
Note the information regarding transport and storage of the device.

Transport
For transporting the device, use the bag included in the scope of delivery in order to protect the device from external influences.

Operation

Inserting the battery

Note

Make sure that the surface of the device is dry and the device is switched off.

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
Please 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).

⇨ The device switches on.
⇨ The 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:

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.

Switching the laser pointer on/off

Using the laser button (7) you can switch the laser pointer on or off.

1. Press the laser button (7).
   ⇨ The laser symbol is displayed in the Laser indication (11).

2. Press the laser button again to switch the laser off.
   ⇨ The laser (1) is switched off.
   ⇨ The laser symbol is no longer displayed in the Laser indication (11).

Info
The device memorizes the selected setting when switching off.

Changing the display °C / °F

1. Press the °C / °F button (5) to change between the units for the measured values.
   ⇨ The selected unit is shown in the temperature unit indication (14) of the display (8).

Disposal

Always dispose of packing materials in an environmentally friendly manner and in accordance with the applicable local disposal regulations.

The icon with the crossed-out waste bin on waste electrical or electronic equipment is taken from Directive 2012/19/EU. It states that this device must not be disposed of with the household waste at the end of its life. You will find collection points for free return of waste electrical and electronic equipment in your vicinity. The addresses can be obtained from your municipality or local administration. You can also find out about other return options that apply for many EU countries on the website https://hub.trotec.com/?id=45090. Otherwise, please contact an official recycling centre for electronic and electrical equipment authorised for your country. The separate collection of waste electrical and electronic equipment aims to enable the re-use, recycling and other forms of recovery of waste equipment as well as to prevent negative effects for the environment and human health caused by the disposal of hazardous substances potentially contained in the equipment.

In the European Union, batteries and accumulators must not be treated as domestic waste, but must be disposed of professionally in accordance with Directive 2006/66/EC of the European Parliament and of the Council of 6 September 2006 on batteries and accumulators. Please dispose of batteries and accumulators according to the relevant legal requirements.
