Automatic Buffer Recognition

The automatic buffer recognition system enables users to select the order in which buffers should be used while performing calibration. By employing this method, users can rapidly run their regular calibrations without useless fault messages.

Two Display Layouts

With just a single keypress, users can switch between the uFocus™ layout or the full-information screen, thus preventing users from being distracted by data of less importance.

Connectivity and Peripherals

RS232 and USB interfaces enable users to connect several peripherals from METTLER TOLEDO at the same time, thus enhancing the capabilities of their instrument.

IntelligentSensor Management (ISM®)

ISM® assists in removing mistakes by automatic recognition of the sensor upon connection and guarantees that the latest calibration is utilized for future measurements.
