UNI-T UT528 PAT Tester – Portable Appliance Safety Tester

Description

Product Overview
The UNI-T UT528 PAT Tester is a portable electrical safety testing instrument designed for technicians who need to perform routine Portable Appliance Testing (PAT). Its straightforward three-button interface and large LCD make it practical for testing appliances in offices, commercial premises, schools, workshops and other environments.
Unlike the earlier UT527, the UT528 displays the individual test measurements as well as PASS/FAIL status, giving technicians more information when documenting appliance safety results. tester.co.uk
How It Works
The UT528 provides dedicated test sequences for different appliance categories. The tester applies controlled test conditions to evaluate protective-earth continuity, insulation resistance and leakage. It can also check IEC and extension leads for wiring faults.
The tester operates from six 1.5V LR14 batteries, allowing portable testing without requiring a mains-powered test instrument. pattesters.co.uk

It does not provide internal test-result memory/storage, so results for larger testing programs need to be recorded separately. tester.co.uk Applications The UNI-T UT528 can be used for: - Portable appliance testing - Class I electrical appliance safety checks - Class II appliance testing - IEC power-lead testing - Extension-cord testing - Office electrical equipment - Workshop equipment - School and educational facilities - Commercial premises - Rental and property maintenance - Electrical maintenance inspections - IT equipment safety testing Buyer Guidance The UT528 is best suited to low-volume and routine PAT testing where technicians need individual readings and PASS/FAIL results without requiring automatic test-result storage. The tester is designed as a dedicated PAT instrument rather than a general multimeter or insulation tester. tester.co.uk For procurement, confirm whether the supplied package includes the exact test leads, IEC lead, alligator clip, batteries and carrying case required for your intended testing workflow.
