PLUGSYS pH Measurement Module (pHMM)
Used to measure pH with pH glass electrodes, primarily in biological fluids such as perfusate for isolated perfused organs.
The pH Measurement Module (pHMM) is used to measure pH with pH glass electrodes. The main application is continuously pH recording with the combination pH electrodes for measurement in biological fluids such as perfusate for isolated perfused organs.
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.
