• Microprocessor-controlled stepped pulse current technology

• Automatically controlled background drift compensation

• Most results available within one minute

K90340 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 µg, mg/kg, ppm, or % along with the input parameters (sample ID, number, sample weight, volume delay times, etc.). The end point is detected by AC polarization and indicated by a visual display, a report print-out, and an acoustic beep. Stastical analysis of maximum, mean, and minimum vales can be determined for up to 99 tests. User-programmable calculation modes include weight/weight, weight/dilution ratio, volume/density, and volume/volume. Delay start and end times of up to 30 minutes can be selected. 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.
