Metrohm has combined the best aspects of laboratory and online systems to produce the 875 ProcessLab: a fully customised, automated at-line system for analytical testing.
Determining water levels in lubricating oils
It is impoirtant to determine the presence of water in machinery lubricating oils, which is why Metrohm is offering its 831 KF Coulometer to give reliable results over a long period.
The Metrohm Unitrode sensor (6.0259.100) has been designed for a multitude of different applications.
This combined pH glass electrode has a fixed ground-joint diaphragm, the large surface area of which ensures the sensor is insensitive to blockage by particulates or contamination.
In addition, the glass membrane of the Unitrode electrode is suitable for most conditions including high alkali and is resistant to high temperatures.
This is because they are made from a specialized U-glass membrane which has been developed to have a very low alkali error and temperature resistance.
The new 6.2323.000 Storage Solution (patent pending) has been developed to solve this very problem.
If a combined pH glass electrode is kept in this solution then the performance of the glass membrane does not change with respect to the response time and the alkali error.
If c(KCl) = 3 mol/L is additionally used as the reference electrolyte then the optimized composition of the storage solution guarantees that the pH glass electrode is always ready for immediate use.
Conditioning prior to the measurement is not necessary, no matter how long the electrode has been stored.
Therefore by replacing your cheap ceramic pin diaphragm electrode with a Unitrode and storage solution will reduce the number of electrodes you get through and may turn out to be more cost-effective in the long-run.
