Abstract

A sensor for the continuous monitoring of pH in sea water, having the configuration of a probe, is described. The characteristics of this probe, which uses phenol red adsorbed on Amberlite resin as a chemichromatic element on top of an optical fibre, are reported and the effects of interfering parameters (variable salinity and temperature of sea water) are assessed. The possibility of enhancing the working range is discussed, and a procedure for rendering the range suitable for marine monitoring is presented. © 1990.
