Automatic titrator with exchangeable head

With its performance spectrum, the automatic titrator TitroLine® 7000 is the ideal starting device for all potentiometric titrations with potential for expansion and automation.
Thanks to the high-resolution and precise pH/mV and “dead-stop” measuring interface, it is possible to determine a wide range of parameters quickly, reliable and accurate. The easy exchangeable burette heads with a size of 5, 10, 20 and 50 allows a quick change between the different titrants.

The TitroLine® 7000 with has an exceptional 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/µA and temperature are clearly displayed on the display.
