OCMA-505 Oil Content Analyzer


The OCMA-505 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-505 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-505 offers easy operation, and can detect even oils with low boiling points.


    Color graphic LCD
    The OCMA-505 comes equipped with a 3.5-in color graphic LCD. Menus and measurement data can be clearly seen
  • USB flash memory drive port
    Storing data on USB flash memories enables easy data management on PCs.

  • Backlit extraction tank (patent applied for)
    The extraction tank is equipped with LEDs. Illuminating the tank makes it easy to check the phase separation between sample and solvent.

  • Unit conversion
    Inputting measurement conditions can change the units displayed (mg/L, mg/kg, mg/g, and mg/PC) as the user needs.
