Quick and easy measurement in approximately 3 minutes^*1
Measurements can be made easily and quickly by simply pressing the start button. Compared to the n-hexane method, measurement times can be significantly reduced.
*Excluding time for activities such as warming, calibration, rinsing

Capable of measuring low-boiling point oil components
The n-hexane method requires the evaporation of the oil extraction solvent, which leads to volatilization of low boiling point oils (such as gasoline). The OCMA-500 series eliminates the need for an evaporation process, allowing for the prevention of volatilization in low-boiling point oil components.

Oil content can be displayed as a concentration (value)
Unlike the n-hexane method, which calculates concentration by measuring the weight of oil content, OCMA-500 can directly display oil concentration.
*Please contact us for inquiries regarding the types of oil that can be detected.

Environmental-friendly, safe, and cost-effective oil extraction solvents are in use
The domestic model OCMA-505-H/555-H uses solvent H-519 for oil extraction, while the international model OCMA-500/550 uses solvent S-316. Both H-519 and S-316 are not regulated under the Montreal Protocol (Ozone Layer Protection Act) and the PRTR system (Act on the Evaluation of Chemical Substances and Regulation of Their Manufacture, etc. (CSCL)). Furthermore, compared to the traditional solvent H-997, solvent H-519 has achieved similar regeneration efficiency to solvent S-316, allowing for a reduction in running costs.
