K90350 Portable 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.

Features and Benefits

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

• Microprocessor-controlled stepped pulse current technology

• Two portable models specifically designed for either crude oil and petroleum products or transformer and insulating oils


K90350 Portable Coulometric Karl Fischer Titrator
The Koehler Portable Coulometric Karl Fischer Titrators are designed specifically for the petroleum/petrochemical and power generation industries. The titrator systems are pre-programmed to provide accurate results with minimal operator training and utilize a microprocessor-controlled stepped pulse current for automatic determination of the appropriate titration speed depending on the amount of water present in the sample. The titrators display and print out the test results in g, ppm, or % along with the input parameters (sample ID, number, sample weight). Supplied complete with a rugged carrying case, glassware, built-in printer and a calibration certificate, the systems can be transported with the reagents in the titration cell and ready for immediate use upon arrival on site. System mobility is further enhanced by flexible power options from either the built-in battery pack, main power supply, or an automobile power outlet. 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 power supply.
