Everything you need to ensure all electrical equipment and systems are fit for purpose and safe to use, including insulation, earth and RCD testers and portable appliance testers. Carry out electrical maintenance safely, with protective measures in place with the help of lock-out kits, voltage testers and proving units, as well as thermal cameras to avoid you having to get too close to live parts. We supply instruments from leading brands like FLIR, Fluke, Martindale, Megger, Seaward, plus RS PRO. And remember, for even greater confidence we can calibrate your new tester before shipment to ensure accuracy of measurements.
