Simple and fast to use, reliable and robust, compact handheld PAT100 PAT testers from Megger are said to be the ideal choice for carrying out low- to medium-volume testing in offices, shops, business units and similar environments. Their tough construction means that they are also suitable for use by training organisations.

The testers are currently available in three models —  PAT120, PAT150 and PAT150R. All are complemented by a smartphone/tablet app, which is available for Apple and Android devices. The app provides a concise guide to PAT testing, including risk assessment, determining re-test frequency and cable calculations for extension leads.

The series provides all of the functions needed to carry out tests on the majority of commonly encountered portable appliances. The PAT120 offers insulation testing at 500V by default, but a 250V option, which provides safe testing for IT equipment and surge-protected devices, can be selected at the start of each test. 

For users who need to test an even wider range of portable and fixed equipment, the PAT150 offers all of the functions of the PAT120 plus many others. The additional functions include tests for 10mA and 30mA portable RCDs and separate tests for continuity, insulation, leakage and SELV equipment, all of which can be accessed rapidly via the quick-test button.

With the PAT150, mains-powered leakage testing is also supported, and live-circuit measurement is available for testing the mains supply and socket polarity as well as for measuring voltages up to 300VAC. Experienced users can quickly and easily adjust test group pass limits and test durations to suit special requirements, and the resistance of the bonding leads can be nulled to minimise measurement errors.

Key features and benefits

  • Three models are available — PAT120, PAT150 and PAT150R.
  • Hardened, scratchproof glass protects the display and rubber armouring for the cases.
  • The testers are suitable for carrying out low- to medium-volume testing.
  • They feature pre-programmed test groups with fixed pass/fail limits for testing Class I and Class II appliances as well as extension and power leads. 
  • With the PAT120, leakage testing is carried out using the ‘substitute’ leakage method, which removes the need for access to a mains supply while performing the test.
  • The PAT150 offers all of the functions of the PAT120 plus many others.
  • The PAT120 and the PAT150 can be powered by AA-size alkaline cells or NiMH rechargeable batteries.
  • The PAT150R offers identical functionality to the PAT150, but has provision for recharging NiMH batteries without removing them from the instrument.
  • Instruments in the new PAT100 series comply fully with all relevant UK and European requirements for electrical safety testing.
