"A pH monitor that may be included in either a portable or bulkhead-mounted system. It consists of a highly reproducible free-diffusion liquid junction which reduces the usual liquid junction potential error encountered with electrode systems. A capillary liquid junction is formed between the reference reservior (containing the silver/silver chloride electrode) and the pH cell (containing the pH electrode and the sample to be analysed). Capable of extreme accuracy and long term stability, giving a precision of +/- 0.01 pH unit across the salinity range 1 to 40 ppt combined with temperature precision to 0.02 deg C."@en .
