Description

Karl Fischer Titration is the specific standard method for water content determination and gives accurate and precise results within minutes.

One Click™ User Interface

• Large color touchscreen (VGA 5.7 in. color TFT, 640 x 480 pixel) with simple-to-understand and fast-to-operate One Click user interface
• All users have their own homescreen with dedicated shortcut buttons (12 per user) to directly start specific routine tasks
• User interface in English, German, French, Spanish, Italian, Chinese, Russian, Polish, Korean and Portuguese available

Diaphragmless Cell

• Choice of a current generator cell with or without a diaphragm
• Diaphragmless cell offers more convenience for most samples as there is no catholyte needed
• Due to the unique design, the diaphragmless cell even meets the demands of very precise low water content determinations

Solvent Manager for Safe Handling

• Protects users against contact with chemicals
• Takes care of filling, draining and exchange of reagents
• It is controlled by the titrator and full security is guaranteed by overflow protector in the waste bottle

PC software LabX™ Titration

• Connectivity to LabX Titration PC software via USB or direct Ethernet (TCP/IP)
• Full control over the titrator, secure database archiving, networking, efficient result management with control charts and individual search filters or rapid and clear method development for new applications
• Complete traceability by providing user management, audit trail, method history and electronic signature

Flexible Data Export

• Devices such as printers, memory sticks, USB hub or USB barcode readers can be connected via the USB port and are automatically recognized
