UE Systems Ultraprobe 401

Manage your lubrication program with the Ultraprobe® 401 Digital Grease Caddy Pro and reduce bearing failure.


The Ultraprobe® 401 Digital Grease Caddy Pro translates ultrasound into the audible range enabling users to hear and recognize bearing sounds while simultaneously viewing decibel levels on a display panel. Users can monitor the amount of lubricant being applied and know when to stop; preventing over-lubrication. Useful Features
