Titroline 5000 Modul 2, 20 ml/50 ml



The TitroLine® 5000 is a very compact titrator for simple routine titrations. Thanks to a selection of standard methods to choose from, the creating of methods as you go is no longer required. Just load the method you need and press the start button. GLP compliant results with titration curve can be documented on a connected printer or USB-memory stick.

The TitroLine® 5000 is the can be used in the food and beverage industry but also for dedicated analysis in other industries.

The TitroLine® 5000 with has a high visibility full color graphic display which allows viewing even at extreme angles. The titration curve, but also other information such as ml, pH/mV and temperature are clearly displayed on the display. This way of working makes the TitroLine® 5000 the perfect titrator for the analysis of parameters such as FOS/Tac thanks to innovative features and ease of operation – all without sacrificing accuracy.

The two USB and two RS 232 interfaces makes the TitroLine® 5000 very communicative. Various USB devices such as printers, barcode readers, keyboards can be connected. Analytical balances can also be connected to transfer the sample weight automatically to the titrator. Results are documented in PDF and CSV format on a connected USB stick.
