Control of oxygen content in gaseous media

METTLER TOLEDO Advanced Line Oxygen Sensors are specifically designed for reliable, on-line measurement of dissolved oxygen in sterile/clean processes. The high surface finish achieved during the manufacturing process of the InPro6800 sensors ensures full compliance with EHEDG and FDA guidelines for surface treatment of equipment for hygienic processes.

Modular design saves time and costs !

  • The unique design of the sensor’s inner housing greatly simplifies the replacement of the anode/cathode module, greatly reducing maintenance costs.No more complicated maintenance procedures – the quick coupling allows you to replace the inner case in less than five minutes!Reliable connection is ensured by a special housing design.
    Guaranteed high process reliability
    • Durable materials, robust construction and easy replacement. The unique Ingold membrane, designed and engineered by METTLER TOLEDO, has become the de facto industry standard for quality.
    High degree of protection against pollution
    • The new O2 sensors have been tested by leading test labs to ensure they fully comply with all regulatory requirements. METTLER TOLEDO sensors are the world’s first EHEDG (European Hygienic Design Group) certified oxygen sensors to fully comply with 3-A hygiene standards.
    Compatible with any transmitter
    • InPro6800 sensors are fully compatible with 4100e “Advanced Line” oxygen transmitters. METTLER TOLEDO “Advanced Line” transmitters offer a wide range of benefits. With ease of use, rugged construction and a full range of essential features, the Advanced Line transmitters are ideal for the most demanding applications.
