If condensate forms frequently at the same spot, it usually doesn't take long until mould grows as well. Used for private purposes or commercially – the high-quality pyrometer dew point scanner BP25 provides you with the opportunity to check surfaces such as interior walls and facades for cold spots with a high mould growth potential. Infrared non-contact surface temperature measurements at walls can be carried out quickly and easily; the dew point temperature is automatically determined at the same time. Even in unfavourable lighting conditions the measured values can easily be read on the neatly arranged backlit LC display. The measuring spot is displayed on the respective material to be measured by means of the integrated 20:1 dual laser.

In order to determine the dew point, the device additionally measures the current room temperature and the humidity level in the air. When it comes to larger measuring surfaces, the BP25 with its acoustic and visual alarm function, which is based on the traffic light principle, as well as its integrated bar graph indicator offers you quick information on whether or not the dew point at the measuring location has been reached or even fallen below and comes with an increased risk of mould growth due to condensation. Mould begins to form on material surfaces when they are exposed to an increased relative humidity of approx. 70 % for longer periods. For this reason, the BP25 warns you both acoustically and visually several degrees before reaching the actual dew point. So it pays to inspect cold spots at the wall with the BP25 in order to detect any condensation forming at an early stage.

Keeping an eye on the measuring spot at all times thanks to the 20:1 measuring optic

Using the infrared pyrometer BP25 you can measure the surface temperature of walls, materials and objects without the need for contact. To enable you to better estimate the location and dimensions of the measuring spot, the BP25 comes equipped with a dual laser pointer. It projects two laser dots indicating the measuring spot diameter on the surface to be measured. An infrared sensor measures the temperature value in this area, then an average value is determined. Bear in mind: the smaller the measuring spot, the more precise the measuring result – and the greater the distance between measuring device and measuring object, the larger the measuring spot diameter. Owing to its geometric resolution of 20:1 the hand-held measuring device yields accurate measurements even from a distance of a few metres.
