Product Details

Megger PAT150 Handheld Portable Appliance Tester

Offering straight-forward, reliable and efficient appliance safety testing for portable and fixed electrical equipment, the Megger PAT150 PAT Tester is ideal for use in most environments with a low to moderate PAT testing requirement and enables you to carry out PAT testing in full compliance with the IET Code of Practice.

With additional mains powered tests available such as earth leakage testing, touch current testing and portable RCD testing, as well as test sequences for Class I, Class II appliances and extension leads, the Megger PAT150 Tester also carries out earth continuity testing at 200mA, insulation testing at either 250V or 500V and substitute leakage testing.

Additionally the Megger PAT150 provides a separate test for SELV (Safety Extra Low Voltage or Class III) appliances.

With adjustable PASS limits and user-configurable test durations, the Megger PAT150 can also null Bond lead resistance to reduce measurement errors, making it an incredibly versatile non-downloading PAT Tester.

Live circuit measurement is also available for testing the mains supply and socket polarity or electrical circuit voltage to 300V (AC).

Encased in rugged rubber armour and fitted with toughened “Gorilla” glass, the Megger PAT150 is incredibly durable and its battery powered operation makes it ideal for those locations where an electrical supply isn’t available or where a mains powered PAT tester would prove impractical.

The Megger PAT150R PAT Tester is also available which has an inbuilt battery charger, preventing the need to remove the AA batteries from the tester to recharge them externally. To purchase this model, simply select the option above.

Megger Part Number: 1003-064 / 1003-428 (rechargable model)
