pH Probe Amplifier

View Full Size Image View Original Datasheet pH Probe Amplifier

pH Probe amplifiers require buffer amplifiers with an input impedance greater than 10^13 ohms. Without loading the probe, an output of approximately 60mV/pH unit is produce. The thermistor is added to provide first order compensation for the inherent temperature coefficient of the pH probe output.
