Charge Measurement Unit JCI 178
Compact, battery powered instrument for measurement of small quantities of charge. 20nC and 200nC FSD sensitivity with resolution to 10pC on most sensitive range. May be fitted with JCI 179 Discharge Probe for measurement of charge transfer in spark type discharges.
Faraday Pail Adaptor JCI 177
The charge received by the pail of a JCI 147 Faraday Pail unit can be measured with a JCI 178 Charge Measuring Unit using a JCI 177 adaptor disc. This gives sensitivities of 20nC and 200nC full scale with opportunity for remote electronic zeroing.
Discharge Probe JCI 179
Shielded discharge probe for measurement of current and charge transfer in spark type discharges. 25mm hemispherically ended probe with 3mm sensing probe tip. BNC connector for coax cable connection or direct mounting to JCI 178.
Zero Check Chamber JCI 152
A 200 mm diameter 250 mm high gold plated brass chamber for setting and checking zero of JCI 131 fieldmeters.
Earth Bonding Cord JCI 157
'Durable Dot' and crocodile clip type terminations for easy earth bonding of JCI Static Monitor and associated instruments. Coiled cable extendable to 2m with integral 2M resistors.
