The HI4000-51 is a replacement pH reference assembly for the HI4101 ammonia gas sensing ion selective electrode.
A gas sensor works due to the partial pressure of the measured gas in solution. The dissolved gas in the sample diffuses into the membrane and changes the pH in a thin film of unbuffered electrolyte on the surface of the internal pH sensor. Diffusion continues until the partial pressure of the sample and the thin film of electrolyte are the same. The pH change is proportional to the concentration of dissolved gas in the sample solution.
