A coulometric Karl Fischer analyser for trace-water measurement in compatible samples. Automatic electrolysis, stirring, drift compensation and endpoint detection provide results in water mass, concentration or percentage.
Features
- Coulometric Karl Fischer measurement from 1 ppm to 10% water content.
- Closed titration cell reduces exposure to ambient humidity.
- Automatic electrolysis-current and drift compensation.
- 7-inch colour touch-screen interface in English.
- Result calculations including mean and standard deviation.
- Integrated thermal printer with dated sample results.
- USB and RS232 computer connectivity.
Applications
Petroleum and insulating-oil moisture testing; chemical analysis; pharmaceutical quality control; compatible solvents and electrolytes.
