The moving-coil meters of the PR series are suitable for measuring DC currents or DC voltages. The moving-coil movement is manufactured according to the latest findings and is characterised by low power consumption, high accuracy and particularly good damping. The units can be installed in switchboards, mosaic grids (except PR 144x36) or machines. On PR 96x24 the bezel, the front glass and the scale are easily replaceable, as is the incandescent lamp for the scale illumination (option). A strain relief for the connecting cables is integrated at the rear.
