The FlowCell COND 4UPtF Arc is a high-precision conductivity sensor for inline process monitoring. Featuring a four-electrode platinum design, it provides accurate and stable measurements across a wide conductivity range. Hamilton’s Arc intelligent sensor technology enables direct digital communication to eliminate external transmitters and simplify system integration.
