UNI-T UT527 PAT Tester Details

This entry level PAT tester is perfect for testing both class 1 and class II appliances. It can also be used to test cables and power sockets, and uses a simple interface to give efficient results.

Since this is an entry-level product, things are kept simple. The device clearly tells the user when a test pass/fails, and is perfect for PAT engineers who don’t feel comfortable with more advanced equipment.

The interface also contains a simple, three button system. These three buttons allow you to choose the correct type of test and the device will then tell you should you select the wrong one. The UNI-T UT527 takes all the complicated processes out of PAT testing, allowing you to easily assess multiple items in an environment in a quick and efficient manner.

In terms of tests, the UNI-T UT257 is capable of performing earth continuity, insulation resistance and live/neutral checks for o/c, s/c and crossed.

If you’re worried about your device getting damaged while on the move, this package also comes supplied with a hard transit case, allowing you to move your tester safely between jobs.
