TitroLine® 7500 is a automatic coulometric titration system for water determination according to Karl Fisher (KF) in a typical range of 1ppm - 5%. Coulometric water determination allows for measurement of very low water concentrations without the need to determine the concentration of the titrant. Ideal for use in chemical and pharmaceutical industries. For direct titration in the glass titration vessel, the sample needs to be either liquid or in gas-form. Water from solid samples and high viscosity samples needs to dissolved or extracted externally prior to titration.

The system features 50 different methods where the parameters can be adjusted individually. TitroLine comes with USB, RS232 and ethernet interfaces for connection and communication with a variety of instruments, such as printers, barcode scanners, precision balances and other SI Analytics units. TitroSoft software is required for direct use with a pc.

• Coulometric KF titration with automatic drift determination and correction.
• Standard methods for different applications such as determination of water in %, ppm, water with KF oven and others.
• Statistical functions including average value and relative standard deviation.
• Configurable data output: Short, standard with curve and GLP.
• Can also be used to measure bromide number.
