DISCONTINUED ITEM-Replacement Model: Horiba OCMA-550 Oil Content Monitor

Compact and easy to use, the OCMA-350 oil content analyzer provides quick, accurate measurements in the lab or in the field. The instrument measures the amount of oil in water, soil and machined parts for a variety of applications. Some common applications include waste water effluent, bilge water discharge, oil/water separators, contaminated soil and oil on textiles and metal parts. The OCMA-350 uses an excellent extraction solvent called S-316.

  • The instrument measurement takes 30-60 seconds using a solvent for the extraction and NDIR method.
  • The use of a quartz sample cell keeps the instrument clean from possible spills.
  • Oil is extracted using the extremely stable S-316 solvent extractant.
  • Users can display analysis results in three different units-mg/l, mg/kg, and Abs.
  • The instrument has an easy-to-read backlit liquid crystal display.
  • RS-232C interface is standard equipment.
  • Environment: Surveying water quality and hazardous waste sites
  • Industry: Monitoring wastewater influent and effluent
  • Marine transportation: Checking bilge and ballast discharge
  • Petroleum processing: Monitoring the efficiency of oil/water separation processes
  • Oil depots: Monitoring the discharge produced when cleaning storage tanks
  • Automotive: Monitoring waste-water discharge from service stations
  • Quality Assurance: Measuring residual oil on textiles and metal parts.
