Pressure-resistant biotech and pharmaceutical probes with integrated RTD

The InPro 3100 is a combined pH probe and temperature sensor designed specially for in-line pH measurements in bio-processes where CIP and SIP are used. This rugged gel-filled probe leads the industry for fast and precise measurements, even after repeated autoclaving or sterilization cycles at 140°C (284°F). The probe utilizes METTLER TOLEDO’s patented silver-ion trap, keeping the reference junction clear even in the presence of sulfide-bearing solutions.
With the InPro 3100UD, upside-down mounting is possible.

Features and Benefits
Accurate pH probe for biotech applications 
Fully autoclavable and in situ sterilizable pH probe with EHEDG certificate. InPro 3100 is a well-proven probe with a fast response time and impressive long-term stability. 
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
