LY-2100 Fully Automatic Karl Fischer Water Content Tester
Coulometric Method · 1 ppm – 100% · Result in 60 s · 7-Inch Touch LCD
The LY-2100 adopts the globally recognized Karl Fischer coulometric method — the most accurate moisture testing method at low cost. It quickly analyzes water content in liquids, solids and gases from 0.0001% (1 ppm) to 100%, with auto-stirring and analysis completed within 60 seconds. The fully closed titration system protects operators from reagent, and one 500 ml Karl Fischer reagent bottle supports about 1000 consecutive tests. Widely used across petroleum, chemical, power, pharmaceutical, pesticide and research institutions.
