A Ph Probe Buffer Amplifier
Buffer amplifier is required by a typical pH probe to isolate its 10^6 to 10^9 ohm source resistance from external circuitry. Such an amplif...
Ph-probe-and-detector
The greatest sensitivity is achieved if R1 is approximately equal to the probe resistance. The circuit can be zeroed with R2, while the ful...
