Solid-state instrumentation for use with optical-fibre chemical-sensors.
A solid-state instrument has been developed for use with optical-fibre pH-sensors, which incorporates light-emitting diode sources and a photodiode detector. The instrument has an internal reference. The optical and electronic principles are described. The responses of the sensor and instrument are reported and compared with those obtained with conventional instrumentation.
