F460 - 4 Channel Precision Electrometer with High Voltage

Industrial ControlCurrent Measurement


The F460 is a 250kHz 4 channel nano-ammeter well suited for quadrant or segmented detectors. The F460 can calculate beam position real-time and servo using on-board analog outputs.

An on-board high voltage source can power an ionization chamber, low voltage bias, or an electron suppression ring.

The F460 can also operate as four separate electrometer channels. The dynamic range allows it to measure the low currents from a Faraday cup like the BC-75. The F460 has a high enough range to measure the microamps of currents in FLASH therapy.
