Save energy and have a healthier home.The PTD1 has three diff erent measuring modes that you can quickly switch between at the push of a button. All you have to do is set the type of surface you want to inspect (emission ratio) by allocating the surface to one of the three preset groups. Now you can perform your measurement and will then instantly receive a clearly arranged readout of all important measuring parameters and results on the illuminated display. If the PTD1 discovers a thermal bridge or mould risk when evaluating and interpreting the measurement data, the three-colour warning light will alert you to this.
