although the volumetric KF titration can determine low levels of water,it is generally accepted that coumometric KF titrations are more accurate for routine determination of very low levels of water. as a general rule, if samples routinely contain water concentrations of 500Mg/kg or less,the coumometric tech should be considered.

ASTM E203 Volumetric Karl Fischer Titrator

KN-203 Volumetric Karl Fischer Moisture Titrator


    KN-203 Volumetric Karl Fischer Titrator conforms to ASTM E203 Standard Test Method for Water Using Volumetric Karl Fischer Titration. It is an automatic volumetric Karl Fischer titrator with high accuracy, great flexibility and repeatability. The titrator is designed to perform titrations for a variety of sample types/matrices, allowing the user to obtain both good results and high-speed analysis. The KN-203 analyzes for water content ranging from 100 ppm to 100%. This powerful titrator automatically dispenses the titrant, detects the endpoint, and performs all necessary calculations and graphing.



  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.
