| Summary: | A simple low-cost portable optical fibre chemical sensor instrument has been
developed in this study by using a laser diode as a light source and solid-state
photodiode as a detector. This inexpensive device is shown to have a good
response and can be used in three different liquid acid-base titration studies Le.
strong acid-strong base, strong acid-weak base and weak acid-strong base, by
using a suitable pH indicator. The results obtained by using this instrument
were found comparable with titration data obtained by using conventional pH
meter. |
