The HSE-HA Electrometer module is a high-impedance electrometer plug-in amplifier for the PLUGSYS measuring system. It is used to measure continuously concentrations with potentiometric electrochemical sensing electrodes. The main application is recording of pCO2 or Na+, K+ and Ca++ concentrations in biological fluids such as perfusate for isolated perfused organs, using the corresponding electrodes. The input circuit of the module includes an isolation amplifier (potential separation between sensing electrode and circuit ground of the PLUGSYS measuring system) to avoid measurement errors due to ground loops and leakage currents.
