The measurement time is too long. Any suggestions?
Measurements
in waste water are always tricky. Believe it
or not, "waste" is the problem! Sulfides
are a big problem. They block the reference
diaphragm…bad diaphragm, bad electrode. pHil the
frog has a number of hints for you, check them
out!
Routine measurements For routine measurements in the laboratory,
the Metrohm 827 pH lab is the instrument that best serves your
needs. Depending on whether automatic temperature compensation
is required or not, you can use the Metrosensor Unitrode (6.0258.010)
with integrated Pt1000.
Precision measurements For precision measurements in the laboratory
choose the Metrohm 780 pH Meter which lets you take advantage
of
Metrohm's unique automatic electrode check, issue reports and a
calibration reminder. Depending on whether automatic temperature
compensation is required or not, you can use the Metrosensor electrodes
6.0258.010 (Unitrode with integrated Pt1000).
In the field you want a robust electrode with fast response and
a handy, easy to use pH meter. Your system: the Metrohm 826
pH mobile and a Metrosensor Unitrode (6.0258.010) with integrated
Pt1000.
