    Metrel OmegaPAT Plus MI3305 PAT Tester

    The Metrel OmegaPAT Plus MI3305 PAT Tester is Metrel's most comprehensive tester! The OmegaPAT Plus is a Dual Voltage PAT Tester suitable for periodic testing, troubleshooting or as a tool for electrical safety in workshops. The tester can operate on both 230V and 110V supply voltage and is enclosed and well protected in a robust and waterproof case.

    The tester itself has taken speed and ease of use into consideration, and has over 100 pre-programmed Auto Tests built into the tester. These test sequences will cover almost any type of appliance you will be testing, and it makes PAT testing a lot easier and quicker. Should you require any other Auto Test sequences, the user can programme and store up to 50 additional Auto Tests on the Metrel OmegaPAT Plus. The tester is also equipped with a QWERTY keyboard for rapid data entry. Test results and PAT data is stored on the tester (the OmegaPAT Plus stores up to 6800 results) and can then be downloaded onto the Patlink Pro Software using a USB or RS232 download lead. Download leads and software comes supplied with the tester.

    Using the PATLink Pro Software enables viewing and advanced analysing of PAT results. Test reports can be compiled and printed off or converted and e-mailed in pdf, excel or other file formats. Appliance data can also be uploaded using the optional PATLink Pro PLUS software when re-testing appliances. This means that you would not need to re-type any information into the PAT tester when re-testing an old appliance. When memory has been uploaded back onto the tester you can recall that information by using either the QWERY keyboard or the optional Barcode Scanner. This rapidly speeds up the testing procedure when testing the same appliances more than once.

    The Metrel OmegaPAT PLUS can also carry out Flash Testing (Dielectric Testing) on 1500V and 3000V AC, which is the main difference between the MI3305 OmegaPAT and MI3304 BetaPAT Testers.

    The long term reliability of this PAT tester is guaranteed by Metrel's 3 year warranty. The OmegaPAT Plus PAT Tester is ideal for anyone who needs a fully comprehensive downloadable PAT Tester that has efficiency and speed of testing as a priority.
