Alcomax Magnets

Dial and Movement Assembly

The Avometer Mk 2 meter movement has "Alcomax" magnets, which are the red coloured blocks that produce magnetism. At the time of manufacturing, these were the most powerful magnets available.

Although most meter movements follow the Weston design, one of the aims of a meter manufacturer is to make their meters as sensitive as possible. This is when the movement is capable of producing a full-scale deflection of the needle with the smallest of currents. This is achievable by using a powerful magnet, which has many lines of flux, known as high flux density.

One major difference between the AVO 7 series and AVO 8 series is the magnet technology employed in their movements, and the reason why the AVO 8 has a greater sensitivity.
