OCMA – 500

Oil Content Analyzer

OCMA-500 to measure concentration of oil contained in drainage and environmental water.
After injecting the water sample and solvent, all you must do is press the start button, and the system will automatically conduct the monitoring operation from oil extraction to sample measurement and draining. With no more troublesome operations like opening/closing the drainage valve, monitoring is speeded up. In addition, the colour graphic LCD and the backlit extraction tank have improved operability.






  • Backlit extraction tank
    The extraction tank is equipped with LEDs. Illuminating the tank makes it easy to check the phase separation between sample and solvent and set the extraction time.

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


  • Reduction of environmental impact and running cost
    The OCMA-500 cuts solvent consumption by 20% compared with our previous products, reducing environmental impact. It also reduces the running cost.

  • Measurement mode
    Measurement can be switched automatically or manually.

【Auto mode】
Stirring, measurement and draining are automatically conducted after injection of the sample.

【Manual mode】
You can conduct measurement operation at any timing while checking the extraction state.

■Example of manual mode
