Customer Profile

The Nantong Customs Service Center purchased the VicoMeter WKT-A9 precision Karl Fischer moisture analyzer. The WKT-A9 uses the Karl Fischer coulometric principle to rapidly determine trace moisture down to 0.001 ppm, measuring trace moisture in solids, liquids and powders within 1 minute. It has a built-in printer, stores 500 data sets, and supports real-time query and printing! Innovative navigation-style prompts and a built-in electronic manual simplify operation. The WKT-A9 complies with multiple national and international standards, with eight built-in moisture calculation formulas and 6 measurement methods, widely used in chemical, petroleum, pharmaceutical, electric power, food, scientific research and testing industries—a Karl Fischer moisture analyzer for mid-to-high-end applications.

Coulometric (coulometry) principle, ideal for trace-level testing; 5-inch color touchscreen with smart operation, automatic result calculation, and freely configurable sample IDs; complies with multiple national standards and suits virtually every industry.

  • 8 moisture calculation formulas, 6 determination methods, and 8 end-point detection algorithms

  • Automatic drift compensation, automatic subtraction of ambient and background moisture, and self-diagnostic fault alerts

  • One-touch start for reliable results

  • Outstanding automation — connects seamlessly to the Karl Fischer oven for difficult samples

  • RS232 interface for connection to a PC, printer, PLC, or LIMS


VicoMeter at the Customer Site

After arriving on site, the VicoMeter technical engineer first confirmed with the customer that no accessories were missing, then began normal installation. Installation went smoothly, and the engineer then began reagent conditioning.

After loading the reagent, the engineer conditioned it with pure water and ran verification with 2 µL of pure water; the result was 1972 µg. The customer already had two VicoMeter Karl Fischer coulometric moisture analyzers and was very familiar with the instruments, so the engineer briefly introduced the new features and the customer was quickly up and running.

China is now a major import and export country, and quality testing is indispensable for exported products. The adoption of the VicoMeter WKT-A9 by a national authority fully demonstrates our strength. 

With technological development and the advancement of Chinese manufacturing, requirements for technical parameters keep rising. VicoMeter is committed to providing the most professional moisture analysis solutions for all industries.

Karl Fischer Moisture Analyzers Karl Fischer Moisture Analyzers

A Karl Fischer moisture analyzer is an instrument designed on the Karl Fischer method to measure moisture content in materials. It is also known as a Karl Fischer moisture meter, fully automatic Karl Fischer moisture titrator, intelligent Karl Fischer trace moisture analyzer, or Fischer-method moisture meter, and comes in two types: coulometric and volumetric (titrimetric).

What Is the Difference Between Coulometric and Volumetric Karl Fischer Titration? What Is the Difference Between Coulometric and Volumetric Karl Fischer Titration?

The biggest difference between the volumetric and coulometric methods is that I2differ in their source: in the volumetric method, I2comes from the titrant reagent, while in the coulometric method, I2is produced by electrolyzing an electrolyte containing I-is generated by electrolysis of the electrolyte.

Which Samples Can a Karl Fischer Moisture Analyzer Test? Which Samples Can a Karl Fischer Moisture Analyzer Test?

As a classic moisture determination method, Karl Fischer titration is suitable for measuring water in a wide range of organic and inorganic substances. Because compounds vary in their properties, they fall into two categories: those that can be analyzed directly and those that cannot.

What Calibration Standards and Verification Methods Are Available for Karl Fischer Moisture Determination? What Calibration Standards and Verification Methods Are Available for Karl Fischer Moisture Determination?

VicoMeter Karl Fischer moisture analyzers are typically calibrated and verified using standards such as methanol-water standard solutions, water-containing sodium tartrate, distilled (deionized or pure) water, and water-saturated toluene. This article introduces the calibration substances, calibration methods, and accuracy verification procedures commonly used with VicoMeter coulometric and volumetric Karl Fischer moisture analyzers.

How to Ensure Moisture Reacts Fully with Karl Fischer Reagent How to Ensure Moisture Reacts Fully with Karl Fischer Reagent

As a professional instrument for moisture determination, the Karl Fischer moisture analyzer is widely used across industries. Ensuring that moisture reacts fully with the Karl Fischer reagent is the key to accurate moisture measurement in samples. How can this be achieved? That is the question this article answers. As an expert in the moisture field, VicoMeter walks you through it.
