Trotec BP25 Infrared Dew Point Thermometer

The Trotec BP25 is a handheld infrared laser dew point temperature pyrometer for measuring surface and air temperature, dew point and relative humidity.

The BP25 is designed to locate and determine potential low dew point temperatures on materials and surfaces where condensation may occur, resulting in mould formation. e.g. un-insulated walls of homes.

It is also popular for use in determining the dew point of road surfaces when applying asphalt.

As it used primarily as a "dew point scanner" in residential and commercial structures, it features a lower infrared temperature measuring range when compared with the popular the BP21 and TP7 models. The measuring range is -50 deg C to +260 deg C.

Laser pyrometers are used to determine the temperature of a solid surface. Simply click the trigger button and measure the temperature.

As well as displaying a dew point temperature readout, the BP25 also features an LED colour visual and acoustic alarm for low readings. The common "traffic light" colours of green, yellow and red indicate the safe, risk and low values.

Unlike the BP21, TP7 and TP9 models, there is NO adjustable emissivity correction on the BP25. Should your application require emissivity adjustment, please see the BP21 and TP7 models.

Ideal for the measurement of HVAC, asphalting, insulation, food industry etc.
