Megger PAT420 PAT Tester

description

technical info

Part of megger’s PAT 400 range the PAT 420 testing machine is part of the latest generation of test equipment, which features a high duty cycle allowing for quick testing and continuous use all day long.

Built for the modern engineer the PAT 420 is specifically designed for easy downloading to a computer. The ability to properly manage and analyse information from a site inspection can be vital to a PAT company’s growth as it allows for the management of a company’s clients as well as printing of PAT certificates.

The PAT 420 features the unique re-start technology allowing this device to be moved around a site and restart to the same menu saving an engineer’s time and increasing productivity. Another time saving feature of this tester is the five soft touch buttons allowing for the most commonly used functions to be recalled both quickly and accurately.
