Product code: FE165
The pH Amp is a dual front-end suitable for use with pH, ion-selective and potentiometric redox electrodes.
Overview
The pH Amp is a dual front-end suitable for use with pH, ion-selective and potentiometric redox electrodes. The unit is capable of measuring pH in the range 0-14, electrode voltages to 2.0 V and temperature in the range of 0 to 100 °C. It can also be used for temperature compensated measurements or as an independent temperature sensor. The unit is supplied with a RTD Temperature Probe.
