  • Description

    Megger TM200 Digital Timer

    The Megger TM200 Digital Timer is a compact instrument designed for maintenance work in medium-voltage substations. It complements several other Megger products and is easy to carry alongside larger pieces of test equipment. It can time a number of different operations over a range of 0 to 999.999s with a voltage mode and contact mode for truly comprehensive testing. Readings are extremely precise (1ms resolution) and accurate to ±0.02%.

    User-friendly operation on the Megger TM200 means that is very easy to use across several different fields. Readings are shown on the simple digital display and the casing of the timer is extremely durable so it can withstand the bumps and scrapes of regular use. An AC/DC adaptor is supplied as standard alongside a rest lead set, protective cable and transport case.
