Karl Fischer Titrators and Moisture Analyzers

Complete Moisture Analysis & Titration Solutions

Karl Fischer Titrators and Moisture Analyzers are industry-leading analytical instruments designed for precise water content determination in chemicals, pharmaceuticals, petroleum products, food products, polymers, batteries, and many other materials. Even trace amounts of moisture—measured in parts per million (ppm) or parts per billion (ppb)—can negatively impact chemical reactions, reduce product quality, damage sensitive electronic components, and affect material performance. As one of the most trusted moisture determination techniques available, Karl Fischer titration continues to deliver exceptional accuracy and reliability for both quality control and research laboratories.

Karl Fischer moisture analysis is available in two primary techniques to address a broad range of testing requirements. The Volumetric Karl Fischer method is ideal for samples with higher moisture levels, typically ranging from approximately 100 ppm to 100%. This approach directly titrates the sample with Karl Fischer reagent, providing fast and dependable results for routine moisture testing applications. The Coulometric Karl Fischer method is specifically designed for trace and ultra-trace moisture determination, measuring water content from approximately 1 ppm down to 0.001 ppm. By generating iodine electrochemically within the titration cell, it delivers outstanding sensitivity for low-moisture samples.

When combined with advanced potentiometric titration techniques for acid-base, redox, precipitation, complexometric, and non-aqueous analyses, Karl Fischer systems provide a complete solution for modern laboratory moisture and titration requirements.

Qualitest offers a comprehensive range of Karl Fischer titrators and moisture analysis systems designed to support demanding laboratory environments. The QKF-C30 and QKF-C9 provide fully automated volumetric Karl Fischer titration with moisture detection sensitivity down to 10 ppm, delivering accurate, repeatable, and efficient moisture analysis across a wide variety of applications.

Measure Moisture. Control Quality. Enhance Precision.

In industries where moisture content directly impacts product quality, process stability, and regulatory compliance, accurate moisture analysis is essential. A single inaccurate Karl Fischer result can delay quality-control approvals, compromise product performance, create compliance challenges, or disrupt manufacturing operations. Laboratories that consistently achieve dependable moisture data rely on advanced Karl Fischer titrators designed for exceptional sensitivity, repeatability, and compliance with recognized international testing standards. The Qualitest QKF™ and QualiAPT™ product lines provide the precision and confidence required for critical analytical applications.

Whether analyzing pharmaceutical ingredients, evaluating lithium-ion battery electrolytes, monitoring transformer-oil quality, conducting polymer research, or performing routine acid-base and potentiometric titrations, Qualitest offers analytical solutions tailored to a wide range of laboratory requirements. From the efficient QKF-C30 volumetric Karl Fischer titrator to the high-sensitivity QKF-A9 trace-moisture system and the versatile QualiAPT™-1000 automatic potentiometric titrator, each instrument is designed to deliver accurate, repeatable, and efficient analytical performance. Backed by responsive technical support and application expertise, Qualitest helps laboratories maintain confidence in every measurement.
