- My electrode doesn't last. Help?
- 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.
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).
Field measurement
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.
