K90300 Coulometric Karl Fischer Titrator


Test Method
Determines low concentrations of water in a wide range of liquid, gas and powder samples. Used for assessing water content in petroleum and petrochemical products including oils, gasolines, solvents, and fluids as well as other products such as pharmaceuticals and cosmetics.

Features and Benefits

• Conforms to ASTM D4928; IP 386; API Chapter 10.9

• Microprocessor-controlled stepped pulse current technology

• Automatically controlled background drift compensation

• Most results available within one minute


K90300 Coulometric Karl Fischer Titrator
The Koehler Coulometric Karl Fischer Titrator utilizes the latest measurement technology featuring a microprocessor-controlled stepped pulse current for automatic determination of the appropriate titration speed depending on the amount of water present in the sample. As the end point is approached, the titration speed is reduced for obtaining accurate test results. The titrator displays and prints out the results in g, ppm, or % along with the input parameters (sample ID, number, sample weight, volume delay times, etc.). Background drift is automatically compensated during the titration and all displays/printouts can be programmed in several different languages. Up to 10 individual methods can be stored in memory for easy recall. The titrator is suitable for use in the laboratory or the field. The built-in battery pack provides up to 8 hours of continuous power for remote operation and is automatically recharged when the unit is connected to a main power supply. The titrator is supplied with glassware, built-in printer and a calibration certificate.
