Overview

The OCMA-310 is an automated portable unit for monitoring oil content in both fresh water and saltwater. The one-touch monitoring process is fully automated, from sample extraction to analysis and sample expulsion. The OCMA-310 utilizes an S-316 extraction solvent to ensure superior oil particle stability and infrared absorptiometry for sample analysis. Using 0mg/ l -200mg/ l dynamic ranging, the unit is capable of analyzing both high and low concentrations. The OCMA-310 provides swift, highly accurate analysis of the oil content of both fresh water and saltwater as well as that of such fluids as those found at factories and wastewater treatment plants.

Features

* A microcomputer provides automated analysis of the samples at the touch of a button.
* Dynamic ranging provides analysis from 0mg/ l-200mg/ l without manual switching.
*
The use of an S-316 extraction solvent ensures the highest levels of oil particle stability.
* A digital display eliminates the misreading of analysis results. A visual display alerts users to the unit' s operating status.
* The use of a proprietary syringe ensures a fixed amount of sample water and solvent.
