AELAB Karl Fischer Titrator AE-KFT-40C | Precise Water Content Analysis

A Karl Fischer Titrator is a lab instrument used to accurately measure water content in solids, liquids, and gases. It operates based on the Karl Fischer reaction, where water reacts with iodine in the presence of sulfur dioxide and a base, usually methanol. The titrator includes a vessel, electrodes, a burette, and a stirrer. The sample is mixed with the reagent, and the endpoint is detected either volumetrically or coulometrically, depending on the titrator type. Results are shown as water content, typically in ppm or as a percentage. This instrument is widely used in industries like pharmaceuticals, chemicals, food, and petroleum to ensure product quality by precisely measuring moisture.

Feature:
1.LCD display screen.
2.Support KF Titration Mode and Titer Detection Mode.
3.Features of auto-filling, auto-purging and auto-mixing of the reagents ensure safe handling of Karl Fischer chemicals.
4.Selectable units including mg, mg/L, %, ppm, etc.
5.Settable parameters, including measurement unit, polarization current, stirring rate, titration rate, stop volume, endpoint potential, stop criterion and etc.
6.Store up to 200 titration data sets (GLP-compliant).
7.Data can be easily transferred to printer via RS-232 commnication interface.
8.Reset feature automatically resumes all settings back to factory default options.

🔬 How It Works?

The AE-KFT-40C uses the Karl Fischer reaction where water reacts with iodine, sulfur dioxide, and a base in methanol to precisely measure moisture content. The sample is mixed with the reagent in the titration vessel, and electrodes detect the endpoint volumetrically. The LCD screen displays the water content results in units like mg, ppm, or percentage, making the process clear and straightforward for lab professionals.
