Abstract: | The use of ‘of the shelf’ microcomputer hardware and software and a new type of laboratory style combination pH electrode with a built in preamplifier makes it possible to monitor pH shifts in a group of experimental vessels in a time frame of seconds without resorting to expensive smart switch boxes or multiple pH meters. A data acquisition system is described for monitoring pH shifts. |
