  • Description

    Take care of safe power tools!    

    The Sonel PAT-820 electrical equipment safety meter is used for measuring the parameters of electrical equipment, including power tools and household appliances, as well as parameters which determine their safe use - resistance of protective conductors, insulation resistance, continuity of connections, leakage currents, power and parameters of RCD switches. The meter presented here is additionally equipped with the Flash test / high voltage test function. The device is intended especially for facility maintenance departments, maintenance services, service companies performing measurements of power tool parameters, hotels and public institutions. The PAT range of meters is proving its worth in areas where ensuring the safe use of power tools is one of the key elements in protecting the user from electrical shock.

    Digital PAT-820 meter is designed for parameter measurements of all kinds electrical devices, such as power tools, household appliances, etc. The device is dedicated to the facility maintenance departments, companies providing power tool measurement services, hotels and public institutions services. PAT should be used in every place where the safety of using power tools is one of the inseparable elements of taking care of the user’s safety against electric shock.

    Device capabilities

    The PAT-820 device thanks to the advanced measuring unit enables comprehensive testing of power tools. Due to the expanded interface, it enables the recording of large amounts of measurement data, and the use of additional functions to facilitate work. Support for QR code scanner, label printer or communication with PC is not a problem. The measurements are carried out in an intuitive and widely configurable manner.

    Intuitive operation

    The large, touch screen and graphic layout makes work on the device is intuitive and pleasant. The built-in help guides the user when building the correct measurement system. The work related to data records is based on a tree- structure memory that enables the construction of a transparent and extensive database.

    Have duty housing

    Durable case with IP67 protection (with closed lead). It provides reliability during measurement, transport and storage.
