WATER CONTENT MEASUREMENT

Pocket Titrator KF

Precise determination of water content by direct injection of the sample into the measuring cell – a truly portable coulometric Karl Fischer analyser.

Precise determination of water content by direct injection of the sample into the measuring cell. The Pocket Titrator KF is a truly portable, easy-to-use coulometric Karl Fischer analyser. Its high-performance microprocessor automatically controls all electrolysis settings – the titration rate adjusts itself to the amount of water to be titrated.

Pocket Titrator KF – explainer: measuring water content in insulating oil

Water is the silent enemy of every transformer. Just a few ppm in the insulating oil accelerate ageing and reduce dielectric strength. The Pocket Titrator KF measures water content precisely – using coulometric Karl Fischer titration. In an instrument that is truly portable. The oil sample is injected directly into the measuring cell – without any elaborate preparation. At the platinum electrode, iodine is generated, which reacts with the water. Automatic electrolysis control adjusts the current by itself. Once all the water has reacted, the indicator electrode detects the end point – and the result is ready: in micrograms, ppm or percent. Sensitivity is below 1 ppm – with a measuring range of up to 100 %. Operation is by touch display, measurement with a single click. And with battery and car adapter, it weighs just one and a half kilos. Pocket Titrator KF. Water content under control – with Energy Support.

Features

All benefits at a glance

Coulometric KF titration

Precise determination of water content by direct injection of the sample into the measuring cell with low background drift.

Automatic electrolysis (AEC)

The microprocessor controls all electrolysis settings automatically – the titration rate adapts to the amount of water.

“One-click” measurement

User-friendly pocket software with preconfigured methods – measurement with a single click.

High precision

High accuracy even at the lowest water concentrations – sensitivity smaller than 1 ppm.

Short analysis time

Infinitely variable electrolysis current for very short analysis times.

All KF reagents

Suitable for all commonly used Karl Fischer reagents and a wide range of applications.

Process

How the measurement works

From injection to result in just a few steps – the Pocket Titrator KF controls the titration fully automatically.

01

Inject the sample

Inject the oil sample (0.001 – 10 ml) directly into the measuring cell – without elaborate preparation.

02

Titrate automatically

The automatic electrolysis control (AEC) adjusts titration current and rate by itself.

03

Detect the end point

End-point indication via square-wave AC polarisation, shown visually on the display.

04

Read the result

Output of the water content in µg, ppm (mg/kg) or % – via Windows printer if required.
