Fischer Porosity Tester Offers Variety

A new porosity tester from Fischer Technology offers a way to test enamel coatings of various thicknesses on a variety of substrates, the company announced.

The POROSCOPE HV20 is used to detect pores and pinholes in electrically non-conductive protective coatings on metal or concrete using the High Voltage Method according to ISO 2746, ISO 8289 and DIN 28055.

Testing helps ensure that coatings of steel tanks, agitator vessels, boilers, pipes, mixers and other parts are free of pores, cracks and defects that could allow exchange between the equipment and its contents.

Coatings can be tested on a variety of surfaces with the available electrodes, including flat brushes, sweepers, or smaller whisks for the inside of cavities.

Poroscope tester

Fischer Technology's POROSCOPE HV20 has an adjustable range of voltages and numerous safety features for high voltage testing.

The porosity tester is ideal for high-voltage testing of the coatings often used on equipment and infrastructure in the chemical and petrochemical industries, according to Fischer. Testing to verify the integrity of the coating should be performed right after the enameling process.

Adjustable Voltage

The HV20 has an adjustable range of 4-20 kV, and the correct voltage, based on values laid out in the ISO 2746 standard, can be set directly on the probe head. The voltage can also be set according to the disruptive strength and thickness of the coating.

As the electrode passes a defective spot, the voltage drops briefly and a sparkover as well as an optical and acoustical signal indicate the pore.

Safety Features

The design of the probe head meets safety requirements for working with high voltage, the company says. With the high voltage being directly generated in the probe head, a high voltage cable is not necessary. In addition, high voltage is switched off automatically if the instrument is overloaded for a long period of time.

The POROSCOPE's isolated handle, covered in a metal housing, is connected to the instrument ground, preventing electrostatic charging of the operator. An integrated protective resistor limits the current to a non-dangerous level in case of an electrical shock, according to Fischer.
