Oil Content Analyzer

Fully automated one-touch operation, from oil extraction to sample measurement and draining

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.

How to measure:

OCMA-500 Oil Content Analyzer - Measurement


  • 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.


Improvement of operability:

  • 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.


Before extraction                 After extraction
*The color depends on the sample.

  • Color graphic LCD

The OCMA-500 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.

  • Unit conversion

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