POROTEST 7 pinhole (electric spark) detector
The PoroTest 7 produced by German EPK company is used to detect pinholes and cracks, and can measure all insulation coatings on conductive substrates such as steel, aluminum, etc. The instrument includes a high-voltage probe, a built-in high-voltage generator, and test electrodes. The host is equipped with a digital display screen and a control panel. The host is portable and made of sturdy ABS plastic with a handle. The high-voltage probe and the host are connected by a sturdy cable. When the POROTEST 7 pinhole (electric spark) detector detects, the host automatically sets the detection voltage corresponding to the material thickness. When a pinhole is detected, an electric spark will be released. In addition to electric sparks, the instrument will also emit sound and light alarm signals and record the number of needle holes.

POROTEST 7-pinhole (electric spark) detector is particularly suitable for: internal and external coatings of conveying pipelines, ship hulls, oil tanks, and storage tanks; Ceramic, paint, rubber, and asphalt inner coatings, GFK
And other plastic materials.
