InPro 6000 Sensor Series Oxygen Measurement Sensors Technical Data Short description The InPro® O2 sensor family provides the means for reliable in-line measurement of dissolved and gaseous oxygen in a wide spectrum of processes amongst others under sterile / hygienic conditions. To meet the range of respective requirements, METTLER TOLEDO offers a selection of advanced O2 sensors and measuring systems for the beverages industry, biotechnology and chemical industry. Outstanding features of the O2 sensors are: – hygienic design, capable of withstanding cycles of standard CIP / SIP – stainless steel surfaces with highly polished finish – steam sterilizable and autoclavable up to 140 °C (284 °F) – low detection limit at high signal stability – O-rings with FDA and USP Class VI approval – minimal maintenance requirement – ISM (Intelligent Sensor Management) technology for digital sensors Measuring systems for non-hygienic applications, such as in wastewater/effluent treatment, are also available.
