As impulsive as effective – quick leak detection made easy

The impulse current measuring system PD200 is the ideal solution for the­ ­pinpoint location of grounded leaks in non-conducting sealing systems – e.g. bitumen, elastomer, PE-HD or other ­plastic sheets.

The PD200's weight and dimensions could once again be clearly reduced as opposed to its previous model. Consequently, the PD200 is not only 20 % lighter, it also takes up 30 % less volume in the case, which still holds the full set of PD200 accessories!

In addition to the ergonomic recessed handle integrated in the cover with an inner Grip-Clip for the best hold while carrying the PD200 is also provided with a lateral bar handle for transport.

Due to the user-friendly miniaturization and the transport bar handle providing additional mounting options for instance for ropes, the device can easily be carried onto the roof area even through bottlenecks such as safety ladders.

Despite the reduction in weight, the stability of the PD200 could also be improved once again by manufacturing the housing as a robust, aluminium-based lightweight construction.

- Ideal for pinpoint location of grounded leaks in non-conducting sealing systems
- Non-destructive inspection of foil and bitumen roofs
- Leak detection even in case of flat roofs with superimposed load (e.g. gravel fill, greening, paving etc.)
- Tightness test of hall floor sealing for LAU (storage, filling and handling of substances hazardous to water) and HBV (production, ­treatment and use of substances hazardous to water) systems (WHG – Water Resources Act)

Light, robust, versatile – the PD200 enables reliable leak detections of flat roofs, ­terraces, swimming pools, ponds or landfill liners …

Owing to the compact dimensions and the light weight, the device can easily be transported onto the roof area even through bottlenecks such as safety ladders.		Connections and operating elements of the PD200 are accommodated and well protected inside the case construction, offering sufficient stowage space for further measuring equipment.

The functional principle of the PD200's pulse current method

The PD200’s functional principle is based on the pulse current method where voltage is applied to the foil to be tested: a ring main is installed with the positive pole on the sealing surface and a grounding cable with the negative pole on the bottom side of the respective sealing sheet. Surface moisture serves as conductor for the electric current applied via the pulse generator, the flow direction of which is captured by use of the measuring rods and indicates the direction to the leak position on the pulse receiver. For the application of the PD200 it is irrelevant whether the sealing is gravelled or greened, the only thing that needs to be ensured is a sufficient drenching of the sealing sheet
