Megger MIT2500 50V to 2500V Insulation Tester

Designed to offer long reliable service even when used in tough on-site conditions, the MIT2500 insulation tester features rugged construction, with resilient rubber over-moulding, and an IP54 protection rating. Designed from the outset with safety in mind, it incorporates live circuit detection and protection functionality, and has a CATIV 600 V safety rating in line with IEC 61010. The MIT2500 insulation tester has feedback-stabilised test voltages to ensure that tests are always carried out to Megger’s market leading tight specification. The MIT2500 also incorporates a guard terminal that makes it possible to compensate for the effects of surface leakage currents. The variable mode provides a unique solution for awkward insulation voltage measurement applications. The range option allows an insulation test voltage from 50 V to 999 V in 1 V steps, 1.0 KV to 2.5 KV in 10 V steps. Typical applications for Megger’s new 2.5 kV insulation tester include testing of cables, motors and generators. In addition, as users can adjust the test voltage in 10 V steps from 100 V to 2.5 kV, the instrument can also be used for testing electrical installations, verifying the ESD of materials and testing of control panels, to name but a few.
