Still Using Reusable Dissolved Oxygen Sensors in Single-Use Applications?

Traditional polarographic DO sensors must be inserted directly into the single-use process risking contamination and leakage. Learn how Hamilton optical DO single-use sensors solve this issue and let you keep your sensor run-after-run.

Hamilton's single-use dissolved oxygen monitoring system is comprised of the reusable VisiFerm SU and a single-use optical dissolved oxygen sensor cap. The cap is integrated with the single-use container by the container manufacturer.

Unlike other single-use dissolved oxygen options, Hamilton's reusable sensor element enables a compact and cost-effective measurement solution without sacrificing accuracy or precision. A standard measuring loop consists of a sensor element, which is connected to the VisiFerm SU.
