Rugged, Gel-Filled Electrode Requiring Less Maintenance
The InPro 3100 utilizes a gel-filled reference system with an Argenthal type silver-ion trap, keeping the diaphragm clear in the presence of sulfide-bearing solutions and requiring less maintenance.
Robust & Reliable pH Measurement System
The InPro 3100 has a robust design for reliable pH measurements in bioprocesses such as fermentation or cell culture.
InPro 3100 Is Sterilizable & Autoclavable
The InPro 3100 pH sensor is able to provide consistent fast and accurate measurements, even after repeated autoclaving or sterilization cycles at 140 °C (284 °F).
Precise Measurements in Bioprocesses
While the InPro 3100 is a versatile pH sensor with unique features, it's designed especially for capturing precise in-line pH measurements in bioprocesses where CIP and SIP are used.
InPro 3100i Offers Advanced ISM Predictive Diagnostics
The InPro 3100i with ISM technology offers advanced diagnostics to help manage your maintenance. Plug and Measure technology simplifies both installation and calibration as well.
Versatile pH & ORP Sensor to Meet Application Needs
The InPro 3100 family performs automatic temperature compensation, is pressure resistant up to 6 barg (87 psig) and has a watertight connector. The InPro 3100i measures ORP in addition to pH.
Upside-Down Installation With the InPro 3100 UD
The InPro 3100 UD can be installed at any desired angle. This provides a solution for large vessels, double-jacket vessels and other installations where top- or side-entry is impossible.

FAQs
What is the InPro 3100?
The InPro 3100 is a family of pH sensors that uses a gel electrolyte and an integrated temperature sensor for automatic temperature compensation to ensure fast and precise measurements. Designed with an Argenthal type silver-ion trap reference system, the InPro 3100 will keep the reference junction clear, requiring less maintenance long-term. As a leader in the industry, the InPro 3100 pH sensor can be used in bioprocesses where sensor cleaning and sterilization procedures are required while still maintaining reliable measurements. The InPro 3100i also uses ISM advanced diagnostics to simplify both installation and calibration.
What is the difference between the InPro 3100 and InPro 3100i?
The difference between the InPro 3100 and the InPro 3100i is that the InPro 3100 uses analog technology while the InPro 3100i uses digital ISM technology. ISM advanced predictive diagnostics are offered with the InPro 3100i digital pH sensor to help manage your maintenance. The InPro 3100i gives you a clear display of the remaining lifetime of the sensor, time remaining until calibration is needed, as well as counts of SIP and CIP cycles the sensor has undergone.
What lengths are the InPro 3100 and InPro 3100i available in?
The InPro 3100 and InPro 3100i pH sensors are available in a variety of lengths, optimal for different installation requirements. Available sensor lengths include 120 mm, 150 mm, 225 mm, 325 mm and 425 mm.
What transmitters are the InPro 3100 and InPro 3100i compatible with?
The InPro 3100 family of pH sensors integrate with any appropriate METTLER TOLEDO pH transmitter. These include the M80, M100, M300, M400 and M800 transmitters. The exact transmitter for your application should be selected in consultation with your local METTLER TOLEDO representative.
What ISM features are available with the InPro 3100i?
Intelligent Sensor Management technology offered with the InPro 3100i helps you manage the maintenance of your pH and ORP sensors. The InPro 3100i uses ISM Plug and Measure technology for faster installation and commissioning. With this technology you can calibrate the sensor away from the process, and then quickly swap in a pre-calibrated replacement when needed. The InPro 3100i also provides ISM predictive diagnostics to give you a clear display of its remaining lifetime, time remaining until calibration is needed, as well as counts of SIP and CIP cycles the sensor has undergone.
