Complete Moisture & Titration Solutions

Karl Fischer Titrators and Moisture Analyzers are the gold-standard precision instruments that laboratories worldwide rely on for accurate determination of water content in chemicals, pharmaceuticals, petroleum products, foods, polymers, batteries, and a vast range of other materials. Water contamination — even at trace levels measured in parts per million or parts per billion — can damage chemical processes, destroy electronic components, spoil pharmaceutical products, and compromise material performance. Karl Fischer titration, invented by Karl Fischer in 1935 and continuously refined since, remains the most accurate, reliable, and widely accepted method for moisture determination across regulated and research environments alike.

Two principal Karl Fischer techniques cover the full moisture-content spectrum. The Volumetric method (best for higher water contents from approximately 100 ppm to 100%) titrates the sample directly with Karl Fischer reagent until water is fully consumed — fast, robust, and ideal for routine moisture analysis. The Coulometric method (optimal for trace and ultra-trace moisture from approximately 1 ppm down to 0.001 ppm) generates the iodine titrant electrochemically inside the titration cell, delivering exceptional sensitivity for samples with very low water content. Combined with high-precision potentiometric titration for acid-base, redox, complexometric, precipitation, and non-aqueous chemistries, these techniques form the analytical backbone of modern moisture and titration workflows.

Qualitest offers one of the most comprehensive Karl Fischer and titration portfolios available worldwide. The QKF-C30 and QKF-C9 deliver fully automated volumetric KF analysis with 10 ppm sensitivity. The QKF-A Series covers the entire coulometric spectrum (nine models from A1 entry-level to A9Pro). The QKF-A9 delivers trace moisture down to 0.001 ppm with results in 1 minute. The QKF-V Series and QKF-A9-V2 incorporate fourth-generation Cassegrain heating furnaces and gas-phase extraction up to 300 °C for insoluble, volatile, and heat-sensitive samples that cannot be added directly to the electrolytic cell. And the QualiAPT™-1000 Potentiometric Titrator complements the KF range with fully automatic potentiometric titration for acid-base, redox, complexometric, precipitation, non-aqueous, and pH applications across a 10-inch capacitive touchscreen platform. Together, this portfolio supports every moisture and titration workflow from routine QC to the most demanding R&D applications.

Why Choose Qualitest for Your Moisture & Titration Needs

Qualitest is a globally recognized supplier of advanced analytical instruments, serving customers across more than 80 countries with one of the most comprehensive Karl Fischer and potentiometric titration portfolios available worldwide.

Complete Volumetric + Coulometric Coverage

From the QKF-C30 routine volumetric platform to the trace-level QKF-A9 (0.001 ppm sensitivity), the nine-model QKF-A coulometric series, the Cassegrain-furnace QKF-V/A9-V2 for insoluble and volatile samples, and the QualiAPT™-1000 potentiometric platform — Qualitest offers a single coordinated portfolio that matches every water-content level, sample matrix, and analytical workflow.

Trace Moisture Down to 0.001 ppm

The QKF-A9 Trace Moisture Titrator delivers Karl Fischer Coulometric measurements down to 0.001 ppm — the kind of analytical sensitivity that separates premium battery research, pharmaceutical R&D, and high-performance electronics QC from generic moisture analysis. Combined with 8 built-in moisture formulas, 6 measurement methods, and 500-dataset storage, the A9 is the analytical workhorse of modern trace-moisture labs.

Smart Furnace Technology for Difficult Samples

The fourth-generation Cassegrain heating furnace (QKF-V Series) and cartridge heating furnace (QKF-A9-V2, up to 300 °C) extract moisture from insoluble, volatile, or heat-sensitive samples via gas-phase transfer — solving the testing problems that have historically frustrated battery-material, polymer, and pharma laboratories.

Versatile Beyond Moisture — QualiAPT™ Potentiometric Titration

The QualiAPT™-1000 brings high-resolution potential measurement, intelligent endpoint detection, and a 10-inch capacitive touchscreen to a wide range of titration applications — acid-base, redox, complexometric, precipitation, non-aqueous, potentiostatic, and direct pH measurement — eliminating operator subjectivity by removing the need for visual indicators.

Every Qualitest titrator is designed to meet the most demanding global standards — USP <921>/<731>, EP, JP, ASTM D6304/D1364/D4377/E1064/E203, ISO 760, and many others. This ensures every moisture and titration result is universally accepted, audit-ready, and defensible in customer reviews and regulatory submissions.

Cost-Effective Value & Global Support

Qualitest delivers premium Karl Fischer and titration performance at a transparent, competitive price point — backed by global service, training, calibration support, and stocked reagents and accessories. Worldwide presence ensures expert support wherever your laboratory operates.

Measure Moisture. Master Titration.

In every industry where water content matters — and in modern manufacturing, it almost always does — the difference between a successful batch and a costly failure comes down to the accuracy and reliability of your moisture-analysis platform. A wrong KF reading invalidates the QC release, sends defective product to market, fails an FDA audit, or damages an entire production line. The laboratories that consistently deliver world-class moisture data are the ones equipped with Karl Fischer titrators built for sensitivity, repeatability, and full international-standards compliance — and the Qualitest QKF™ and QualiAPT™ portfolios give you exactly that.

Whether you are testing pharmaceutical raw materials, qualifying lithium-ion battery electrolytes, monitoring transformer-oil dielectric quality, supporting fundamental polymer research, or running routine acid-base titrations alongside KF moisture, Qualitest has the analytical platform engineered to meet your exact needs. From the entry-level QKF-C30 to the trace-level QKF-A9 and the versatile QualiAPT™-1000, every Qualitest instrument delivers world-class performance backed by industry-leading service and support.
