Mettler Toledo pH Sensor InLab Expert Go-ISM

Mettler Toledo 51344102 InLab Expert Go-ISM pH Sensor – 0 to 14 pH, Integrated Temperature

The Mettler Toledo 51344102 is a premium, 3-in-1 pH sensor engineered for high-performance measurements in both the laboratory and the field. Featuring Intelligent Sensor Management (ISM) technology, this probe stores calibration data and sensor history, which is automatically uploaded to the meter to ensure maximum data security and traceability. The InLab Expert Go-ISM is constructed with a robust PEEK (Polyetheretherketone) shaft and a solid XERYTOL electrolyte, eliminating the need for refilling while providing excellent chemical and mechanical resistance. With its integrated NTC 30 kΩ temperature probe and open junction design, this sensor provides rapid, accurate readings even in complex samples such as emulsions, suspensions, and low-ion wastewater.

Technical Performance and Design

• Intelligent Sensor Management (ISM): Simplifies operation by storing calibration data directly in the sensor chip, ensuring the most recent calibration is used regardless of which meter the probe is connected to.

• XERYTOL Solid Electrolyte: A maintenance-free, non-refillable electrolyte that prevents junction clogging and maintains stable reference potentials in difficult or dirty samples.

• Robust PEEK Shaft: The high-performance thermoplastic shaft provides exceptional impact resistance and chemical stability, making it ideal for portable use or harsh industrial applications.

• Open Junction Design: Eliminates the risk of traditional ceramic junction clogging, ensuring a consistent and fast response time in "messy" media like dairy products, paints, or cosmetics.

Key Benefits & Applications

• Field and Portable Testing: The "Go" designation indicates a design optimized for portable SevenGo or Seven2Go meters, providing a rugged solution for environmental monitoring and on-site analysis.

• Complex Sample Analysis: The open junction and solid electrolyte are specifically designed to handle "difficult" samples that would quickly ruin a standard glass-junction electrode.

• Plug-and-Measure Convenience: ISM technology eliminates the risk of using an uncalibrated probe, significantly reducing user error and ensuring compliance in regulated environments (GLP/GMP).

• Long-Term Durability: The combination of a PEEK body and maintenance-free electrolyte ensures a significantly longer service life compared to traditional epoxy or glass laboratory sensors.
