  • Description

    The UT528 PAT tester from Uni-T is a basic and battery powered PAT testing machine that conducts tests on Class I and Class II appliances as well as extension leads using a separate test sequence. Using a simple three button operation the Uni-T is easy to use and handy for individuals who are new to PAT testing and would prefer a simple PAT instrument.

    The Uni-T UT528 carries out the basic required tests upon selection of the appliance type (Class I / Class II / Extension Lead) in an automatic test sequence and displays the readins and PASS/FAIL status at the end of the test. Aside from the basic test requirements the UT528 PAT Tester also has the following features inbuilt:

    • Zero Earth Lead function: Used to zero out resistance built up within the earth test lead to avoid inflated Earth Bond readings as a result.
    • 250V Insulation Test option: In addition to the standard test voltage at 500V, a lower voltage of 250V can be selected. This is ideal when testing extension leads with surge protection.
    • 30m Long Lead Test: Activated when testing extension leads exceeding 30m in lengh. This increases the earth resistance allowance in accordance with guidelines for long extension leads.

    The Uni-T UT528 is capable of testing all standard appliances fitted with a 230V plug and all standard 230V 13A extension leads and IEC leads. Using a low test current exclusively at 200mA  the Uni-T UT528 is also safe for testing any IT equipment.

    The UT528 comes supplied in a card plastic carry case that holds the instrument and basic accesories, The kit also includes an earth bond lead with probe and clip, 230V extension lead adaptor, earth nulling adaptor, 6 x C cell batteries and instruction manual. The Uni-T UT528 has been calibrated at time of production but is NOT supplied with a calibration certificate as standard. If this is required then please select when adding to basket.
