DeFelsko Pinhole Detector PosiTest LPD is a handheld non-destructive device for detecting discontinuities in a coating system including pinholes, cracks. DeFelsko PosiTest LPD is a complementary device to inspect non-ferrous coating systems with thickness of less than 500 µm (20 mils). Thanks to its IP65 electronics which are powered by 3 AAA alkaline or rechargeable batteries, you can inspect every surface freely for more than 150 hours on any environment.
The innovative porosity detector works similarly with edy current which are short-circuited to sense the irregularity of coating thickness. Initially, the operator ‘ground’ or ‘earthed’ PosiTest LPD to the conductive substrate by clamping onto an uncoated area. Regulated voltage outputs of low-voltage pinhole test is then performed by rastering a moistened, electrified probe sponge over a non-conductive coating applied to a conductive material. Only if the coating is continuous and no defects are present, electricity is unable to pass from the sponge to the material through the non-conductive coating. But when the electrified sponge encounters a flaw in the coating, electricity is able to flow into the material and travel back to the instrument through the ground wire, completing the circuit and setting off the audible and visible alarms.
Your investment on DeFelsko Pinhole Detector PosiTest LPD will allows your operator to work on detecting quality of surface coating and layer uniformity of liquid container tanks, marine products, pipe and tubes, whether in a workshop or on any manufacturing yard. However if you are also looking for a leak detection of air barrier integrity of single, two-ply and liquid membrane systems with all type of coating, you might also wants to consider DeFelsko PosiTest AIR Surface Tester solution.
