General Description

The JCI 178 is a compact instrument for the sensitive measurement of charge in the range 10pC to 200nC. A special low sensitivity version, the JCI 178X , can be custom manufactured giving the operator the capability to measure up to 200μC.

For measurement of charge transfer in electrostatic discharges the unit can be fitted with a JCI 179 Spark Discharge Probe. This ensures that observations can be interpreted with confidence and valid judgments made on the risk of ignition presented in relation to quantities of charge transferred.
