CVM-780 Contact Voltmeter Set

  • Measure Voltages with Pinpoint Accuracy
  • Ceramic Probe Tips allow Accurate Measurement
  • Reads Real Voltage
  • Valuable ESD Analysis Tool

The CVM-780 Contact Voltmeter™ combines the ease of use of a digital voltmeter with the high input impedance and low input capacitance of a true electrostatic voltmeter in a small, portable, battery operated package.

Being a true electrostatic voltmeter, not a field meter means that it reads real voltage, without confusing it with electrostatic field strength, which can be distinctly different.

The CVM-780 Contact Voltmeter™ uses a unique active probe design which is fully guarded and shielded for minimal interference with the surrounding E field.

The Contact Voltmeter™ is powered by rechargeable Nickel Metal Hydride batteries and is a valuable ESD Analysis Tool.
