Fischer Overhauls Poroscope Line

Fischer Technology has completely redesigned its line of Poroscope portable holiday detectors, the company announced.

The Poroscope Series of holiday detectors discovers and counts defects in electrically non-conductive protective coatings, even defects that aren't visible to the eye, the company says.

Fischer Poroscopes

Fischer announced that it has redesigned its Poroscope Series of portable holiday detectors.

The series includes three versions with three different test ranges:

  • HV5, 0.8 to 5 kV;
  • HV20, 4 to 20 kV; and
  • HV40, 8 to 40 kV.

Multiple Safety Features

According to Fischer, the Poroscopes will automatically adjust the appropriate high voltage. The low-energy high voltage is generated in the probe head, so a high-voltage cable is not necessary. If the instrument is overloaded, the high voltage will switch off automatically, Fischer says.

With the specimen grounded, the electrode is moved slowly across the coated surface. When the electrode passes a pore or crack, a spark jumps across the gap with an acoustic signal, Fischer explains.

The series is equipped with two modes of pore detection: dynamic and static with adjustable thresholds.

An insulated handle covered with a metal housing is connected to the instrument to protect the operator, the company says. The voltage is active only if the instrument is grounded and the push-button switch is pressed. An integrated current-limiting resistor reduces the current to non-dangerous levels, Fischer says.

The Poroscope Series supports various test standards and coating thicknesses. Standards can be set on the unit to automatically adjust the appropriate voltage, according to Fischer. Available electrode styles include brush, flat, sweeper, ring and roller.
