Abstract
Acid/base measuring sensor systems consisting of arrays of basic sensor cells are described which are constructed based on the chemical/electrical response characteristics of poly(aromatic amines). Protonation (doping) or deprotonation (de-doping) of the --N.dbd.sites in the polymers leads to characteristic conductivity vs. concentration curves which can be calibrated to produce reliable, instantaneous readings of the acid/base concentrations at various points in the working environment.
