North Atlantic 213C Series Phase Angle Voltmeters

  • Phase-Sensitive Null Indicator
  • Sensitive AC Electronic Voltmeter
  • Precise AC Radiometry
  • Impedance Meter
  • Power Factor Meter


The North Atlantic 213C Series Phase Angle Voltmeters are solid-state instrument which combines the ability to measure both phase angle and magnitude of complex ac signals and vector components with respect to a reference voltage. Designed for phase sensitive operation at a pre-specified frequency withing 30 Hz to 10 kHz, it utilizes passive phase shifter circuits to assure long-term stability and high accuracy over the spectrum. Front panel controls permit instantaneous selection of voltage ranges and functions.

As a total voltmeter, the Model 213C is capable of measuring signals within a frequency range of 10 Hz to 100 kHz. The Model 213C has its frequency response limited to that if the signal isolation transformer. The signal input voltage, in the transformer mode, is limited to .75f (f=signal frequency in Hertz).

As a phase-sensitive null meter, the 2 μV nulling sensitivity of the Model 213C permits high-resolution ratio-metric measurements. This allows measurement of low-level voltages of the reference frequency in the presence of noise, hum, and other spurious signals. As a phase meter, angles are read on a parallax-free scale calibrated in 1° increments.

The Model 213C also includes a front panel switch for switching the transformer in or out of signal input circuit thereby allowing isolation of either the Reference or Signal channel.

InstraView™ Equipment Inspection

Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
