Customer Profile

The customer purchased three VicoMeter WKT-A9 Precision Karl Fischer moisture analyzers. The VicoMeter WKT-A9 Precision Karl Fischer trace moisture analyzer uses the coulometric Karl Fischer (coulometry) principle to rapidly measure trace moisture in samples, detecting water down to 0.001 ppm and determining trace moisture in solids, liquids, and powders within one minute. The built-in printer and storage for 500 data sets allow real-time query and printout. Innovative guided prompts and a built-in e-manual make operation simple. The WKT-A9 complies with multiple national and international moisture standards and provides eight built-in moisture calculation formulas and six determination methods to meet the moisture testing needs of every industry. Widely used in chemicals, petroleum, pharmaceuticals, power, food, research, and testing, it is a Karl Fischer moisture analyzer built for mid-to-high-end applications.

VicoMeter at the Customer Site

The customer bought three WKT-A9 Precision Karl Fischer trace moisture analyzers at one time for use across its three plants, mainly testing oil samples with moisture around 300–500 ppm. They had previously used the density method, which gave large errors and poor stability. During on-site installation and commissioning, the VicoMeter engineers recommended switching to the mass method, which is unaffected by density and bubbles and gives stable results. They also advised using disposable syringes paired with our dedicated needles: the syringe was rinsed 3–5 times before testing, then 0.4 mL of sample was run in three tests, yielding 421 ppm, 449 ppm, and 437 ppm — accurate, stable results that satisfied the customer.
