Customer Profile

Integrating multiple advanced technologies, the VicoMeter WKT-A6 fully automatic trace moisture analyzer works on the internationally recognized classic Karl Fischer coulometric method. Its measuring range goes down to 0.0001% (1 ppm), and it measures moisture in liquids, solids, and gases within 60 seconds. It is widely used in chemicals, petroleum, power, research, railways, and other industries where moisture content is one of the key quality indicators. Multiple built-in moisture formulas meet different users' needs; the efficient mini printer and large built-in memory store 500 test records, with convenient retrieval so users can easily view and print test reports.

VicoMeter at the Customer Site

The customer had owned the instruments for some time and, having used similar equipment before, did not request on-site installation. The VicoMeter engineer's visit this time was prompted by small problems with both instruments: on the older one the stirrer would not spin, and the newer one could never stop equilibrating.

On site, the engineer first checked both instruments and found the electrodes and titration cells were quite dirty. During cleaning, a black deposit remained on the platinum mesh of the generating electrode of the instrument that would not equilibrate; methanol would not wash it off, so the engineer borrowed the customer's ultrasonic cleaner to clean it. On the other instrument, the stir bar turned out to be larger than normal; a smaller one was fitted and stirring returned to normal.

The engineer then dealt with the second instrument: since the two were identical, the good electrode was swapped onto the instrument that would not equilibrate — after the swap it reached electrolysis equilibrium in under ten minutes, confirming a faulty electrode. The instruments come with stir bars and other accessories matched at the factory, so avoid replacing them arbitrarily. The platinum electrode is a critical component — clean it every time the reagent is changed to extend the instrument's service life.
