npi electronic ION-01M
This amplifier is a plug-in unit for the npi EPMS-07 modular system. It was designed for recording signals from ionsensitive microelectrodes.
The system consists of a main amplifier system and a small headstage with differential input.

Used in all kinds of preparations e.g. single cells, slices or in vivo preparations.
Has a low-noise high common mode rejection (CMR) differential input equipped with ultra-low bias amplifiers (fA range)
Differential input: cmr >120 dB @ gain 100
Input impedance: >100 TΩ; ultra-low BIAS current <100 fA
Input voltage range: 1000 mV DC
Inputs with small headstage, Teflon isolated connector
Integrated electrode holder
Offset compensation for both inputs; range: ±100 mV
C.COMP. for both inputs; range: 0 - 30 pF
Low-pass filter for REF input to improve AC cmr
Output gain: x10 or x100; range: ±12 V
Digital display: XXX.X mV
Electrode resistance test : XXX.X MΩ or XX.XX GΩ
Built-in ramp generator: 1.5 V / s., external signal input available
