I want to measure both pH and ORP at the same time with DrDAQ. Will the external "sensor adaptor" that you sell allow me to connect an ORP probe to DrDAQ.
I think the ORP probe needs a singnal amplifier similar to a pH probe.
Does the sensor adaptor come with such an amplifier, and does it have a BNC connector.
If not, could I use one of the external phone jack connections of DrDAQ, and build a cicrcuit like the one shown here to amplify the sinal using the INA116P Amplifier. Will this work?
