The Rosemount  Hx438 dissolved oxygen sensor provides a drift-free signal and maintains its calibration value for up to 50 steam sterilization cycles. It can be used in the biotechnology, pharmaceutical, chemical, and food processing industries. It uses a 4-pin connection plug for quick disconnection from the cable. It can be used with the insertion or retractable mounting assembly or similar assemblies that are typically used with large scale batch processes that perform SIP cleaning. For smaller batch processes, it can be threaded directly into the top plate and autoclaved if necessary.
