Single-Use pH Sensor - InSUS 307 - Overview - METTLER TOLEDO

Single-Use pH Sensor - InSUS 307

Electrochemical Single-Use pH Sensor

The InSUS 307 single-use pH sensor is designed for integration into single-use bags. This single-use pH sensor covers a pH range from 3-10 and eliminates the need to use two or more optical pH spots.

Reliable Measurement Performance
This single-use pH sensor uses high quality pH sensing technology provided by METTLER TOLEDO's glass pH/reference electrode design.

One Sensor for Many Applications
With it's wide range, this single-use pH sensor can be deployed in many cell culturing and fermentation applications using stirred single-use bags.

Simplifies Bag Handling
The dry storage capability of the InSUS 307 simplifies bag handling, making the technology of this single-use pH sensor easy to use and easy to integrate.

Features and Benefits


Ensure Process Safety
All wetted polymer materials used on the InSUS 307 single-use pH sensor are made of USP class VI certified materials to ensure the highest process safety.


Easy-to-Integrate
The InSUS 307 single-use pH sensor uses a standard 1" Eldon James port disk. This unified design allows for safe and easy installation on a broad range of applications, including cell culturing, fermentation, media/buffer preparation and virus inactivation.


Reliable Output Signals
The output signal on the InSUS 307 single-use pH sensor is identical to the output for METTLER TOLEDO resuable pH sensors. This allows for seamless integration into existing transmitters and biocontroller process environments.
