AC Analog Frequency Meters
The HOYT AC Frequency meters available in 2-1/2", 3-1/2" and 4-1/2" models utilize the high torque bar-ring pivot and jewel mechanism with a solid state frequency network that yields ±2% accuracy of the span. The unit was designed to be less susceptible to errors caused by waveform distortion.
