General description

The modular testo 252 measuring instrument, for
storing, printing and evaluating data via a PC, is
the result of many years experience in the
development and production of measuring
instruments to high standards. It is a complete
system for the monitoring and analysis of water
and aqueous substances (e.g. meat or cheese).
Specialised probes enable the measurement of pH
values, conductivity, redox and temperature in the
respective ranges. High temperatures and/or
extreme pH values can reduce the life of the
electrodes.
These products were mainly developed for
engineers with advanced knowledge and ex-
perience in everyday measurement technology.
We expect those trained in measurement
technology to be able to recognise the tolerances
from the standard conditions and to be able to
assess their effect on the measured result. These
influences are for example calibration and tem-
perature compensation. The following instructions
should, therefore, be of some help.
The new pH Technical Manual containing a
summary on the whole pH measurement
range will be available in Summer ´95:
"pH measuring technology Manual"
(Order no. 0981.3483)
It also contains lots of practical
tips and tricks.
