Introduction
These instructions provide you with a comprehensive overview of the
installation, working principles and operation of the 826 pH mobile and
827 pH lab.
Additional theoretical principles can be found in the Metrohm Mono-
graph 8.015.5013 "Electrodes in Potentiometry".
You can also request our descriptions of applications involving pH
measurements in the form of Application Notes and Application Bul-
letins from your local Metrohm agency or download them from the In-

Instrument description
Both instrument versions, the portable 826 pH mobile and the labora-
tory device 827 pH lab, are used for measuring pH, temperature and
potential reliably. The functional range is identical. The pH meter 826
pH mobile is operated with batteries whereas the 827 pH lab has got
an external power supply.
Up to 200 values can be stored in the memory together with the most
important additional data; these can be viewed and printed as a report.
All stored information (measured values, configuration, parameters,
etc.) can be transmitted via the infrared interface to a printer or com-
puter for output as a report.
