Sinclair Radionics, 1978

The DM450 stood at the apex of the Sinclair range of multimeters, designed for the industrial market. It looked very similar to the lower specification DM350, with a 4.5 digit display and 34 ranges with a claimed accuracy of 0.05%. It was sold by Sinclair (and later Thandar) until well into the 1980s.
