The SX10507 Xwire peripheral board interfaces raw pH probes (no in built preamplifier) to the SPLat Xwire expansion bus. The pH measuring input has a very high input impedance and is optically isolated, to ensure that the pH probe accuracy is not affected by ground currents. In addition it has inputs for a thermistor temperature sensor or a PT1000 RTD temperature sensor. These temperature sensing inputs can be used to temperature compensate the pH value and as well as general temperature measurement. They can be used at the same time.

An on board option link changes the gain of the input amplifier to allow ORP probes to also be used with the SX10507.
