Wet Sponge Pinhole Detector

Caltech India is the leading manufacturer of CES 170 – Wet Sponge Pinhole Detector. This is also known as Multi Voltage Pinhole Detector or Wet Sponge Holiday Detector or Low Voltage Pinhole Detector. The multi-voltage pinhole detector, which uses the wet sponge principle to detect through pinholes, cracks and damaged areas in protective coatings up to a maximum thickness of 500 microns. Pinhole Detector or wet sponge tester detects pinholes, voids, thin spots, foreign inclusions, or contamination in coatings film. Dielectric strength of film also referred as holiday detection. Buy Pinhole Detector with advanced technology, high-quality, and at an economical price.

Model CES 170 is a low voltage holiday detector / wet sponge tester operation is by the application of a wet sponge to the coating. The wetting agent penetrates any pinhole and makes a conductive path through to the substrate, the pin hole detector automatically detects this conductive path and sounds an audible alarm and also gives a visual warning by a flashing red indicator that a pinhole fault has been detected. The flaw can now be marked for repair and further testing resumed. Coating on metals prevents to corrode unless a protective coating is applied. Pinholes based on wet sponge method generally caused by air entrapment that is then released from the surface, or by the entrapment of particulates (dust, sand, etc.), which do not stay in place. High voltage holiday detector is used for testing coatings above 500µm and low voltage holiday detector (Pinhole Detector ) is used below 500µm of coating on metallic substrates.

The Pin-hole multi voltage detectors or wet sponge tester has selectable test low voltages of 9 Volt / 67.5 Volt and 90 Volt which comply with ASTM specifications. Generally 9V will test up to 100 micron, 67.5 Volts will test over 100 to 300 microns and 90 Volt will test up to 500 micron. This wet sponge technique is recommended for paint, epoxy, powder, polymer coatings, plastic, teflon, rubber and non-conductive thin coating to access the quality of coatings without damage to occur to the coating on metallic substrates. Pin hole detectors can be used on painted vessels, pipes and pipelines of curved surfaces, cars, which are coated to withstand a highly corrosive environment s. When the coating thickness exceeds 500 microns, high voltage holiday detectors are recommended. Pinhole / Porosity Standards ASTM G62-A, ASTM G6, ASTM D4787, ASTM D5162, AS3894.2, BS 7793-2, BS EN ISO 8289 A (Wet Sponge Testing), NACE RP 0274-98, NACE RP 0188 and AS1580.485.1 describe the use of pinhole detection and holiday detector. CES 170 Pinhole Detector also confirms to IS 13620 Fusion bonded epoxy coated reinforcing bars.

The pin hole detector / wet sponge tester is supplied ready to use in a carrying case complete with handle / sponge, earth cable and battery fitted.
