Abstract
A potentiometric pH sensor made of graphite, solid paraffin and quinhy drone is described to behave near to reversibility. The slope of the p otential versus pH plot is - 53.06 mV, the standard deviation of measu rements is 0.05 to 0.06 pH units. Unlike the usual glass electrode thi s new pH sensor does not need calibration before use. The sensor can b e made of any shape and size.
