The Deliron cycle indicator is a cost-effective and easy-to-install lubrication monitoring device. It has a custom-machined stainless steel housing and a powerful internal magnet assembly built for industrial use. The Deliron cycle indicator is completely sealed and can accurately monitor fluid or grease systems. The Deliron cycle indicator can be installed on any section and either side of a divider block. The highly visible cycle indicator has a snap-action movement which makes it easy for the user to see as well as determine the precise timing of each divider valve cycle.
