Automatic Karl Fischer Moisture Tester

Weshine factory's durable automatic Karl Fischer moisture tester is a common analytical device built for trace water detection, following the globally recognized coulometric Karl Fischer titration standard. This testing method delivers outstanding sensitivity, making it the go-to choice for measuring ultra-low water content inside insulating oil, petrochemical products, organic solvents and liquid chemical samples.

The machine handles electrolyte balance, titration, endpoint judgment, data calculation and result display all on its own, requiring little manual operation. Stable electrolytic current and fast response bring highly consistent test data batch after batch.

A high-definition LCD screen shows a straightforward operation interface, so operators can adjust test parameters and watch the whole titration process in real time. The internal magnetic stirrer mixes samples evenly, boosting electrolysis efficiency and reading accuracy.

The full titration assembly includes electrolytic cell, measuring electrode, electrolysis electrode, drying tube, sample injection port and stirring component. Premium glass parts resist chemical corrosion and block ambient moisture from interfering with test data.

It is widely adopted by power plant labs, transformer factories, petrochemical workshops, pharmaceutical manufacturers, research institutes and third-party inspection labs, offering quick and reliable moisture detection for routine lab checks and factory quality control.

Working Principle

This quality Automatic Karl Fischer Moisture Tester runs on coulometric Karl Fischer reaction rules. After injecting liquid samples into the sealed titration cell, water molecules inside the sample will quantitatively react with Karl Fischer reagent.

During electrolysis, iodine is produced automatically to combine with water. Once all moisture fully reacts, the machine immediately catches the endpoint, calculates water content and shows final readings without manual math work.

The built-in magnetic stirrer keeps samples and electrolyte fully mixed, maintaining stable electrolytic conditions and reliable repeated test results.
