Automatic buffer recognition

The automatic buffer recognition system allow you to choose the order in which to use buffers when calibrating. This way you quickly get through your routine calibrations without unnecessary error messages.

Two display layouts

Switch with a single keypress between the full-information screen or the uFocusTM layout, in which you will not be distracted by information of less importance.

Connectivity and peripherals

USB and RS232 interfaces allow you to connect various peripherals from METTLER TOLEDO simultaneously, increasing the possibilities of your instrument.

IntelligentSensor Management (ISM®)

ISM® helps eliminate mistakes by automatic identification of the sensor upon connection and ensures that the most recent calibration is used for future measurements.


Compact Printers

No matter which METTLER TOLEDO instrument is connected, you will always obtain a printout that meets the quality standards.

pH Accessories

The integrated temperature probe guarantees you always measure with the right temperature compensation.
The integrated temperature probe guarantees you always measure with the right temperature compensation.

pH Buffer

These solutions are traceable to the primary standards of reference materials selected by NIST.

pH Sensor

PEEK shaft with excellent chemical and mechanical resistance, a robust sensor.
SteadyForceTM reference system is pressurized to prevent the junction from clogging, guaranteeing extremely reliable and reproducible results.
The slim shaft diameter allows measurements of very small sample volumes.
For pH measurement in samples with a temperature down to -30°C.
The extra-long shaft allows measurements in deep vessels, barrels or pilot reactors.
The high electrolyte outflow prevents the pollutants from entering and clogging the junction, which would interfere with the reading.
Measure surfaces like paper, skin or agar plates.
