Oil Content Analyzer

OCMA-550 to measure residual oil on components and concentrations of oil adhered on solids such as soil.
Measurement can be easily made only by injecting the extracted water sample into the attached cell and setting it to the equipment.
This model features a simple design which allows opening/closing of the door to setting of cell with just one hand.
This is best for measurement of extracted samples such as evaluation of residual oil on components and measurement of oil contained in food.


Division: Water Pollution
Manufacturing Company: HORIBA Advanced Techno Co., Ltd.

How to measure:


  • Cell is easily detactable with just one hand
    Simple design which allows opening/closing of door and detachment of cell with just one hand. Measurement operation becomes smoother.

  • Timer function
    A timer function to display a measurement value in a certain amount of time is equipped. This saves work and time required for measurement.


Fully used in Various Applications

Residual oil on components

For quality control of components

For piping of air conditioners and refrigerators

To prevent reduction of cooling function

Semiconductor field

For evaluation of degreasing capacity


Useful for soll (environmental pollution),
food (health hazard) and gas (quality deterioration)
