DISCONTINUED ITEM-Replacement Model: Horiba OCMA-500 Oil Content Analyzer

The OCMA-310 is a portable instrument for monitoring oil content in both fresh water and salt water. S-316 is the extraction solvent required for sample measurements with this NDIR instrumentation. The S-316 extraction solvent can also be reclaimed with the Model SR-305 solvent reclaimer reducing chemical waste and solvent cost. The instrument’s automated extraction chamber allows the user to complete analyses without having to perform a mixing and filtration step to separate the sample from the solvent. The OCMA-310 provides swift, highly accurate analyses in the range of 0-200 ppm.

  • A microcomputer provides automated sample treatment and analysis of the samples with the touch of a button.
  • Sample analysis from 0mg/l-200mg/l without manual switching.
  • S-316 extraction solvent ensures the highest levels of extraction efficiency for accurate analyses.
  • Short warm up time of 20 minutes
  • Instrument diagnosis feature and alarms aid the user with any troubleshooting issues.
  • RS232C and printer ports
  • Environment: Surveying environmental water quality and hazardous waste sites
  • Industry: Monitoring of waste-water 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, metal parts, etc.
