It doesnot matter which method is used. The 885 Compact Oven SampleChanger can be operated with all stand-alone Karl Fischer titratorsthat have a built-in sample data silo*.Easy to useThe 885 Compact Oven Sample Changer is controlled via theintegrated keypad. Only the oven temperature and the gas flow needto be defined and the number of test samples set. That’s how easyand efficient automated Karl Fischer titration can be!Reusable sample vialsScrew-cap vials are used for the 885 Compact Oven SampleChanger. After measuring, these sample vials can be opened andcleaned without any problem and then reused.
