DO Sensor InPro6960i/12/120 - Discontinued Product

Name: DO Sensor InPro6960i/12/120
Brand: Mettler Toledo

Discontinued since: Dec, 2025

The InPro6960i optical oxygen sensor offers high operational availability, top performance and easy maintenance for the measurement of dissolved oxygen in brewery applications.

Material No.: 52206500

High Operational Availability

The InPro 6960i offers outstanding measurement performance with a low detection limit of 0 ppb to 25 ppm, minimum drift and a short response time.

Suitable for Hygienic Processes

The optical technology is available for various brewery applications. It is especially suitable for sterile and hygienic processes in wort aeration.

Advanced Predictive Diagnostics

This DO sensor has Intelligent Sensor Management (ISM) technology, offering predictive diagnostics to reduce maintenance and simplify calibration.

Easy and Fast Operation

With the fast OptoCap replacement and the Plug & Measure ability, the InPro6960i optical oxygen sensor can be calibrated away from the process, and then quickly swapped into the process environment without the need to recalibrate. No polarization is requi

High Process Safety

The materials of construction of the InPro6960i DO sensor are FDA compliant and the easy-to-clean high-polished surface (N5 grade) also satisfies increasing regulatory requirements.

Enhanced Process Control

The sensor's measurement performance helps to reduce out of spec production. ISM helps to make optical oxygen measurement simple and more reliable and significantly reduces the risk of sensor failure during production.

ISM Redefines Maintenance

The built-in digital ISM technology provides the user important information about the sensor wear. Maintenance planning becomes easy, as accurate diagnostics predict when sensor maintenance will be required.
