Overview
Mettler Toledo 51344102 InLab Expert Go-ISM is a premium combination pH electrode engineered for accurate measurements in laboratory and field environments. The electrode features an integrated temperature probe, PEEK shaft, fixed cable and ISM, designed for portable applications in the lab and outdoor with robust and maintenance-free operation. 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.
Key Features
- PEEK shaft with excellent chemical and mechanical resistance, a real heavy-duty sensor
- Thanks to the solid XEROLYT® reference electrolyte, no membrane junction is needed. No junction, no clogging.
- Integrated NTC 30 kΩ temperature probe and open junction design for rapid, accurate readings even in complex samples such as emulsions, suspensions, and low-ion wastewater
- Intelligent Sensor Management (ISM) electrodes capture and save calibration data, which is then automatically recognized by the meter once connected
- BNC (IP67) + RCA (Cinch) plug connection with 1.8m cable length
Technical Specifications
