Insulation testers assess the insulation condition of cables, motors and electrical equipment. They help identify moisture, aging or damage during installation checks, maintenance and troubleshooting.

Earth resistance testers verify whether an earthing system can safely dissipate fault and lightning currents. They support checks of buildings, communications sites and industrial equipment.

RCD testers verify that residual-current devices trip when fault current occurs. They support installation acceptance, routine inspection and maintenance of electrical systems.

Battery testers assess starting and backup batteries, helping identify low charge, capacity loss and failure risk. They support vehicle service, fleet care, UPS maintenance and standby power checks.

Cable tracers locate and identify target cables in complex wiring without disruptive trial-and-error. They support network installation, communications maintenance, low-voltage work and fault tracing.

DC power supplies deliver stable, adjustable power for circuits, modules and electronic equipment. They support development, training, repair and production tests under controlled supply conditions.
