The HPAT400 HandyPAT is an easy to use battery powered, hand-held PAT tester with simple one-button test selection. Its lightweight portable design makes it ideal for testing in all locations whether under a desk or testing a wall mounted monitor.

As well as performing a 500V insulation test, our latest feature now included with the HPAT400 is the ability for users to swap between different test voltages of 250V and 500V. This is especially helpful when testing appliances with surge protected circuits, such as sensitive IT equipment at 250V.

A single button press activates either a full Class I, Class II or lead test without any further interaction required by the user, unless a failure is encountered.
The display has clear PASS/FAIL indicators but does not display test values. Simple connection diagrams are permanently shown on the case body making it easy to start testing straight away.

The HPAT400 delivery contents include an extension lead adaptor, an earth bond probe with clip, 6xAA alkaline batteries and a “TEST & GO” carry case with separate pocket for accessories.
