An Introduction to Trace Moisture Analyzers

The trace moisture analyzer, also known as the Karl Fischer moisture analyzer, is mainly used to test samples with low moisture content. After improvements in recent years, its accuracy has greatly increased and its measurement range has expanded.

The trace moisture analyzer uses the Karl Fischer coulometric titration principle. The Karl Fischer method determines sample moisture with methanol as the medium and Karl Fischer solution as the titrant. It offers high accuracy, good repeatability, and low testing cost; trace moisture analyzers accurately measure trace moisture in samples—liquids, solids, and other substances—and are widely used in electric power, petroleum, chemicals, pharmaceuticals, food, and solar panel cutting fluids. They accurately measure trace moisture in all kinds of liquids, solids, and gases, detecting not only free water but also bound water, and often serve as the standard analytical method for water, especially trace water. They are not suitable, however, for samples containingstrong reducing agents such as VC (ascorbic acid).

When you choose a trace moisture analyzer(also called a Karl Fischer moisture analyzer), you will find that its value is still affected by many different factors，Good materials, for example, are one of them. Many materials can be used to build a trace moisture analyzer, and which grade to choose depends on the material requirements; the service life and usability of the resulting analyzers differ. Choose the right analyzer for your needs and its price will be clear.

The main advantage of the trace moisture analyzer is its imported high-quality humidity sensor, well integrated with the instrument's smart electronics. Measurements are accurate and reliable, with excellent long-term stability and repeatability, immune to most chemical contamination and dust, delivering outstanding performance even in harsh industrial environments. The sulfur hexafluoride (SF6) alarm uses a high-precision sensor as its detecting element—highly sensitive and fast-responding. When it detects that ambient SF6 concentration reaches or exceeds the preset alarm value, it transmits the signal through shielded cable to the controller, which immediately issues an audible and visual alarm; it can also start the exhaust system or close the solenoid valve to cut off the gas source for safety.
