  • Bearing housing lubrication capacity
  • Type of grease used
  • Baseline dB levels
  • dB levels before applying grease
  • dB levels after applying grease
  • amount of strokes of the grease gun used to apply greaseBB_0175
  • cost of grease
  • cost analysis
  • trend bearing condition

Additional useful features of the Ultraprobe 401 Digital Grease Caddy:

  • Two Display Panels (dB & dB with intensity bar graph indicator)
  • Customized settings (with 18 setup menus)
  • Upload/download route data
  • Built-in front-end lamp to illuminate dark areas
  • BB_0022Swivel base adjusts to odd angles
  • Heavy duty headphones for high noise environments
  • Magnetically mounted transducer with docking station (allows lubricating and testing in most environments)
