The Revolution in Insulation Testing

That's the spark: Our unique process revolutionizes insulation tests using conductive films made of polytetrafluoroethylene (PTFE).

With our PTFE Insulation Test Technology – or PITT for short – any surface to be insulated can be tested completely and carefully with a wide range of voltage levels. The patented, extremely robust contact material continues to function even after more than a thousand electric shocks at the same point.

The result: superior efficiency, sustainability and cost-effectiveness.

The Procedure at a Glance

Our Insulation Test: Simply Different

Conventional insulation tests - e.g. of battery cases and cells - are carried out by means of voltage contacting with needles. This method is selective and random and leads to the destruction of the contact in the event of mismeasurements.

However, with PITT we use PTFE films developed and patented in-house by Berghof Fluoroplastics for contacting.

These conductive films are puncture-proof, acid-base resistant and virtually indestructible. Our process is suitable for any surface in need of insulation, regardless of size and voltage level

Unique Advantages


in profitability and sustainability


Contact material can still be used even after many mismeasurements


Inspection of the entire surface, smallest defects can be identified


Testing of any surfaces, sizes and voltages


Contacting of sensitive surfaces


in precision, reliability, flexibility and safety

Universal Application – Customized Design

As the Berghof method PITT is not limited to the testing of battery housings and cells, it is used in numerous industries with a wide variety of test specimens - from automotive components to the insulation testing of household appliances. 

Benefit from long-term, continuous cost savings thanks to the durability of our film and more precise and reliable testing processes

Our innovation is not only revolutionizing quality assurance, but is also an important step towards electromobility and a sustainable future. Thanks to the unique conductive PTFE, we have no direct competitors and our solution declassifies alternative, conventional approaches.
