The PD200 is a professional impulse current measuring system to detect leak (holes) in non-conductive sealing systems and is suitable for leak detection on balconie, pond liners/swimming pools or flat roofs. In contrast to the previous model PD100, the PD200 has extremely compact dimensions - the size of the device could be reduced by more than 30%! These compact dimensions enable the transport of the PD200 e.g. through so-called safety ladders to the corresponding flat roof.The impulse current measuring system easily wins the weight comparison with its previous model. Although the single components partially are pretty heavy (e.g. the transformer), the total weight could be reduced by about 20% (from 11.2 kg to 8.6 kg). On top of the housing there are clearly visible signal lamps - one standard impulse signal (green) and one short-circuit signal (red), incl. integrated tone generator. Tone and lamps are audible and visible from almost every place on the roof and are protected against damages with a robust steel hanger.
