PrimeTest 250
The handheld PrimeTest 250 PAT tester features all of the portable appliance testing electrical safety tests required to meet the IEE Code of Practice including RCD trip time, protective conductor current and touch current.
This portable appliance tester also includes a 250V DC insulation test suitable for testing sensitive electrical appliances and surge protected leads, and can test 3 phase industrial plant and equipment*. Connecting this battery-powered tester to a mains supply allows protective conductor current or touch current measurements to be made automatically.
Using the PrimeTest 250 ensures your portable appliance testing is now quicker and easier because all electrical safety tests are carried out against pre-set limits with measured test result values and clear PASS/FAIL indication on the large display.
