Electrometer Lynx E12
A Faraday cage electrometer with exceptional noise level and rise time.
SEADM offers a Faraday cage electrometer with exceptional noise level (~0.1 mV equivalent to 16 singly charged particles/cm3, with 1 s of signal accumulation) and rise time (~22 ms). It operates based on capturing gas-suspended charged particles or ions on a filter, and sensing them with an amplifier circuit with 1012 V/A. The long time drift of the signal is considerably less than 1 mV in several hours, removing the need for a zero current correction.
