Handheld Insulation Tester

The MT550 Handheld Insulation Tester is a specialised diagnostic tool designed for use in electric and hybrid vehicle service environments where high-voltage safety is critical. It enables technicians to accurately test insulation resistance in EV and hybrid systems, supporting safe diagnostics, maintenance and fault-finding procedures.

Insulation testing is a key requirement in EV servicing to ensure that high-voltage components are electrically isolated and safe to work on. The MT550 provides a portable, easy-to-use solution that allows technicians to verify insulation integrity before, during and after service operations.

Compact and rugged, the MT550 is well suited to dealership workshops, EV training facilities and high-voltage service bays. Its handheld design allows testing to be carried out directly at the vehicle, helping workshops maintain compliance with EV safety procedures and OEM service requirements.
