The SEW electrical testers range at Roshanex covers safety and maintenance instruments for electricians and utility teams. It includes digital insulation testers up to 10kV, 3 wire earth resistance testers and digital RCD and ELCB testers. In addition, you will find high voltage detectors such as the 276 HD and 278HP, plus a battery tester.

Electrical contractors use these instruments to check cable insulation, earthing systems and breaker trips before handing over a job. Meanwhile, utility and grid staff rely on high voltage detectors to confirm lines are dead before work starts. Industrial maintenance teams also use them for routine inspections.
