JCI 114 - Electrostatic Fieldmeter


  • Displays the electric field at the sensing aperture
  • Resolution to 10V/m (20kV/m range)
  • Ranges to 200kV/m
  • Analogue output for data capture
  • Suitable for measuring 50-60Hz AC fields & DC fields.

General Description

The JCI 114 is a compact sensitive instrument for the measurement of electric fields. Sharing the same field mill technology as the JCI 140, there is no need to switch-on in a static free environment, no need for measurements to be made within a limited time and no need to worry about the influence of air ionisation.

The electric field sensitivity at the sensing aperture can be switched between 20kV/m and 200kV/m full scale. Measurements are shown on a 3½ digit LCD with decimal point and low battery indication. An audible alarm gives warning of any electric fields above a user set threshold level.
