The OCMA-500 Oil Content Analyzer has been redesigned for even better operability, maintaining its user-friendly features. After injecting the sample, all you have to do is press a button to get the monitoring operation done quickly, from oil extraction to sample measurement and draining. This machine is easy for anyone to use.The OCMA-500 cuts solvent consumption by 20% compared with our previous products, reducing environmental impact. It also reduces the running costs.



  • Fully automated one-touch operation, from oil extraction to sample measurement and draining
  • Reduced environmental impact and running costs (20% cut in solvent consumption)
  • With no need for a solvent evaporation process, the OCMA-500 offers easy operation, and can detect even oils with low boiling points
  • The extraction tank is equipped with LEDs. Illuminating the tank makes it easy to check the phase separation between sample and solvent
  • The OCMA-500 comes equipped with a 3.5-in color graphic LCD. Menus and measurement data can be clearly seen
  • Storing data on USB flash memories enables easy data management on PCs
  • Inputting measurement conditions can change the units displayed (mg/L, mg/kg, mg/g, and mg/PC) as the user needs.



  • Factory drainage
  • Ballast water, Bilge
  • Vehicle mentenance site and gas station
  • Water quality survey based on environmental standard
  • For monitoring final discharge from petroleum refinery plant
  • For oil dispersion reserch at time of an accident
  • For monitoring final discharge water
