pH Electrode InPro3250

The low-maintenance pH-electrodes InPro3250 Series from METTLER TOLEDO with factory-filled, prepressurized liquid electrolyte are suited to a wide scope of applications in the biotechnology, pharmaceutical and chemical process industries. The InPro3250 series is available with an enlarged selection of different pH-sensitive glass membranes. This guarantees the best possible measurement performance under the most diverse operating conditions.

Features and Benefits

Long operational electrode lifetime and high accuracy
The electrode is provided with a patented silver-ion trap to prevent diaphragm fouling in sulfide-containing media. The internal over-pressure ensures gradual electrolyte outflow efficiently cleaning the diaphragm and preventing influx of process medium into the reference electrolyte.

ISM (Intelligent Sensor Management®)
METTLER TOLEDO's new and innovative, digital "Intelligent Sensor Management®" concept provides "Plug and Measure" functionality. ISM simplifies and improves the operation of process analytical systems from initial installation to maintenance to sensor exchange. ISM technology provides you with advanced diagnostic functions, lower maintenance costs and reduces the risk of sensor failure, while also improving process reliability. More information about ISM

Easy validation
The InPro3250(SG) series offers a set of customized certificates for each application, including certificates for hazardous zones, biocompatibility of the electrolyte, and all relevant hygiene and safety regulations.

Solution ground (SG) as an option
The SG feature as an entire electrode body coating or as a measuring point on a pH-electrode, will improve grounding and effectively eliminate the risk of electrostatic interference. SG also improves our advanced diagnostic functions, and makes parallel pH/redox measurement possible.

More precise pH-measurement
An enlarged selection of different pH-sensitive glass membranes guarantees the best possible measurement performance for example by minimizing zero point shift following sterilization in applications in biotechnology.
