Chauvin Arnoux CA 6505 [P01139714] 500V / 1000V /2500V / 5000V Insulation Tester. The Chauvin Arnoux CA6505 is a comprehensive insulation resistance measurement tool that can be used to measure resistance levels from 10kΩ up to 10TΩ. It is ideally suited for insulation measurements on cables, motors, generators, transformers and more. In addition this device can also be used to measure voltage levels from 1 to 5100V, capacitance from 0.001 to 49.99F and leakage current from 0.000nA to 3000A. It also includes the ability to calculate polarisation index (PI) and dielectric absorption ratio (DAR). The CA6505 is built into its own protective carrying case, making porting between tests quick and easy. The case also protects the tester from damage at all times, ensuring that it can be used in dangerous environments such as industrial areas. Inside the case the CA6505 features a large-size LCD screen which clearly relays testing values.
