ST-2000 Hz Portable Frequency Meter.

The Hz meters use a frequency-to-DC current transducer which drives a high sensitivity moving coil type indicator. It features accurate frequency
measurements without noticeable influence of line voltage fluctuation (50 to 300V) or waveform distortion.

● See Datasheet for Ranges available
● Accuracy : ±0.5% of full scale value on 45 to 65 Hz range
±0.5% of full scale value on 0 to 100Hz range
±0.5% of full scale value on 0 to 500Hz range
● Scale Length : Approx. 135mm (5-3/8”)
● Case Material  : Bakelite with glass window

ST-2000 COS Portable Power Factor Meter.

The PF meter is used for measurement in single-phase and balanced three phase circuits. From a phase discriminating circuits, the output of the builtin transducer produces a DC proportional to the phase between voltage and current to operate the DC indicator.
