Seaward PrimeTest 250 Handheld PAT Tester

 

The Seaward PrimeTest 250 is a comprehensive handheld PAT tester and an engineer's ideal companion. The handheld Seaward 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.

The Seaward PrimeTest 250 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 the battery-powered Seaward PrimeTest 250 PAT tester to a mains supply allows protective conductor current or touch current measurements to be made automatically.

Seaward PrimeTest 250 Handheld PAT Tester Features

• Easy to use manual PAT tester
• Comprehensive range of tests
• Clear PASS/FAIL indication
• Capable of both equivalent leakage (using battery power) and protective conductor / touch current (using mains power)
• Lightweight
• Automatic test sequences
• Ideal for: In-house safety testing engineers, Electrical Contractors and Service & Maintenance Engineers
