323 - Ballantine Voltmeters

Contact for Quote

  • Model: 323
  • Manufactured by: Ballantine
  • High end frequency limit: 25.0MHz
  • Voltage Range High: 300 V
  • Voltage Range Low: 300 uV
  • Extra Specifications: Wideband True RMS AC Voltmeter

The Ballantine 323 True RMS analog ac voltmeter uses advanced true rms circuitry to achieve square law response from rugged, fast responding silicon diode detectors with no thermal lag and overload vulnerability inherent in thermocouple devices.

These true rms meters respond to the equivalent heating power of the waveform being measured, yielding accurate readings for signals from pure sine waves to complex waveshapes such as distorted sines, squarewaves, pulses, noise, switching power supplies signals, and more. Also, when used with instrument shunts, the 323 provides true rms current measurements on non-sinusoidal waveforms.

Using a Ballantine proprietary suppressed-zero logarithmic voltage scale (linear dB scale), the 323 provides constant reading accuracy from end to end, as well as increased resolution and readability.
