Datasheet

Application
The moving-coil panel meters PQ 48/72/96/144 K (K series) housed in
moulded thermoplastic cases are suitable for the measurement of DC
currents and voltages.
The instruments are suitable to be mounted in switchboards, control pan-
els, machine tool consoles and mosaic panels. The bezel, the glass win-
dow and the dial can be easily exchanged on -site.
Movements
Self-shielding moving -coil movements with core-type magnet and
pivot suspension. Spring loaded jewel bearings for vibration and shock
resistance.
