Routine and expert mode      Both operating levels of the DL15 offer advanced users a high degree of flexibility. The expert mode allows you to make fine adjustments to the methods and configurations. A password system prevents the «routine user» from performing undesired operations in expert mode.            Efficient operation with a keypad similar to a mobile phone      Alphanumeric inputs can be entered using a keypad similar to a mobile phone and require no external keyboard. It has never been so easy to input the name of a titrant, to store a method under another name or even to carry out a manual titration. If input fields only allow figures to be entered, the keypad is set by default to “numeric”. This allows you to work that much faster.            Convenient intuitive operation      The user interface guides you intuitively through the menus. If you would like to have methods available at the touch of a button, you can allocate these to the function keys, from F1 to F3. Symbol keys make work considerably easier as they enable operation of the most frequently used manual functions (rinsing burettes, measuring pH values and stirring), all at the touch of a button.            A clear overview provided by results in predefined units      The DL15 automatically calculates results using predefined units. Depending on the method selected, METTLER TOLEDO has predefined the most common calculations using the appropriate units. The results are stored and can be printed out as a clearly structured report via the compact METTLER TOLEDO RS-P42 laboratory printer.            Compact and simple automation with Rondolino      A smart and automated titration stand for automating endpoint titrations alongside the DL15 titrator. Rondolino is extremely easy to install and can be accommodated on a base measuring only 25 x 35 cm, i.e. it requires significantly less space than the typical sample changer. Not only a series of up to 9 samples but also individual samples can be processed quicker since the titration beaker simply needs to be placed on the sample plate. Furthermore, once complete, the electrode is returned to the conditioning beaker.
