InSUS™ pH sensors are gamma irradiation-sterilizable, pre-calibrated single-use pH sensors with an integrated Pt 1000 temperature probe. The sensors have been designed especially for deployment in single-use bags used in biotechnical processes. The sensors offer a design that allows safe and easy installation in a standard Eldon James® port disc with a 1" barb. This port disc is welded into the bag film prior to sensor installation.
