This is an excellent true RMS multimeter that features a large, easily read display and carries an IP67 environmental rating. This means the multimeter is waterproof and will not be damaged if accidentally dropped into water or left out in the rain. The meter has data should and relative measurement capabilities and is housed in a robust, double moulded case. Includes leads, soft carry case and user manual.
