Comprising a stout Bakelite box 100mm diameter with Aluminum diameter. Graduated in 0.90 four times ant parallax mirror slot and replaceable steel pivot. The short magnetic needle has a jewel bearing and a light Aluminum pointer de signed for precise reading and maximum damping. One meter long single piece wooden nicely polished base with embedded 2 half meter scale reading from the centre of compass box (magneto- meter) i.e. zero at centre of both the scales, with compass box Bakelite or Aluminum and leveling screw.

A demonstration meter and may be converted to an AC / Dc voltmeter or ammeter with selection of ranges. For each mode of operated by using one of a services of interchangeable dials which fit through a slot in the side of the case. The movement comprising a high grade-moving coil, galvanometer is housed with in a robust, and all the working parts clearly visible. The scales are marked on both sides of each dial. A zero adjuster permits instruments to be used for centre zero working. Size 320x140x365mm

The primary coil is of 220/230 volts and two interchangeable secondary coils give an output at 6 and 12 volts at 2 amps. Assembly of the transformer and interchanging of coil can be done quickly. Complete with 2meter cord plug connections
