The HTS probe was designed with a virtual ground plane, thus reducing the coil-to-ground losses and making its unloaded quality factor and resonant frequency less sensitive to body proximity. These antennas have low radiation resistance and high reactance, so that their impedance is difficult to match to a transmitter. duplicate those of the AN5525-1 and AN5525-2 probes, having a resistance of 90. The probe is roughly 1:10, as a lot of passive probes. 5082-2804 5082-2836 5082-2815 5082-2826 5082-2912. As it was signalled before, pH meter is nothing else, but precise voltmeter, that measures EMF of the pH electrode. A rheostat in the drain of the MOSFET is used to calibrate the circuit so that each of the three sensor circuits produce the same output voltage for a given value of pH.
