The Crompton Challenger Analog Meter Series are a rectangular style type of analog meter which offers a range of  panel meters with accurate measurement and indication of most electrical and electronic parameters in industry standard (1 1⁄2″ MODEL 361), (2 1⁄2″ MODEL 362), (3 1⁄2″ MODEL 363) and (4 1⁄2″ MODEL 364) case sizes. This innovative design features a detachable lower fascia plate, which allows the flexibility of either surface or window mounting.

The fascia is simply unclipped to achieve the completely flush panel appearance of rear of panel window mounting. The range offers AC and DC ammeters, voltmeters and frequency meters utilising a high torque pivot and jewel movement. AC moving coil rectified meters provide 1.5% accuracy of the full scale value and feature a rear zero adjuster screw for tamperproof installation. AC moving iron meters also provide 1.5% high accuracy and true RMS measurement.
