Insulation tester
Applications
Detect, locate, and fix corrosion damage on plastic-coated tanks and pipelines.
Device description
Gas and water pipelines and underground vessels are exposed to the risk of corrosion. Careful installation is necessary to avoid premature failure and the useful life is extended through careful inspection. This solid device is easy to operate. Test electrodes can be rapidly exchanged. The measurement principle is the low-frequency, high-voltage generated air gap, which in the event of damaged insulation, travels from the conductive surface of the test object. The air gap is clearly visible and audible. A buzzer identifies the point of failure. Damaged sections can be immediately repaired.
Three types power supplies can be used:
- NiCd block
- car batterie
- 220 V 50 Hz AC
A fully charged NiCd-block provides multiple days of measurements. The charge level is optically monitored.
