Oil Content Analyzer - Model OCMA-310

The new OCMA-310 Oil Content Analyzer can assess the amount of trace hydrocarbons in soil or water, as well as check for residual hydrocarbons on pre-cleaned products. The extraction of the oil can be done by Freon 113 and S-316. The S-316 solvent used by the unit may be recycled by HORIBA’s optional solvent reclaimer, making the OCMA-310 very environmentally-friendly. Furthermore, the OCCMA-
310 is quick, easy to use and accurate and reliable.

Manual Control - The two valve system lets you make sure that your sample is measured properly. Inspect your sample and press the extract button to initiate making and separation. You can visually confirm mixing and separation through the sample window. Open the upper valve (extraction valve), and the sample will flow into the measuring cell. An oil/water separation filter prevents water from entering
the cell. An overflow system discharges any excess sample. The lower valve (drainage valve0 allows you to drain the sample after it has been measured.

0-200 mg/l Dynamic Range - The OCMA-310’s pyroelectric sensor gives you a full dynamic range from 0-200 mg/L. This eliminates the need for range-switching and provides fast, accurate measurements for all types of samples, regardless of concentration levels.

Quick Start-up - The OCMA-310 warms up in less than 30 minutes, enabling you to get started quickly.

No Optical Adjustments - The troublesome optical adjustments commonly required by conventional pneumatic NDIR analyzers are no longer necessary.

Auto Hold Function - The unit’s internal computer automatically determines when the measured value has stabilized and maintains that value on the display.

Self-Diagnosis - The OCMA-310 monitors itself for problems such as motor malfunction, deterioration of the measuring cell’s light source, and electrical trouble. Should anything out of the ordinary occur, an alarm light will turn on, and an appropriate error message will appear on the operation display panel.

Oil/water Separation Filter - The OCMA-310 is equipped with an oil/water separation filter which prevents water and dirt from entering the measuring cell. This prevents the cell from being damaged, while insuring that the sample being measured is not contaminated.

Flow Pattern During Measurement
Stage 1
Check that the drainage valve is closed, then open the extraction valve. The sample will flow into the measurement cell where it is measured.
 
Stage 2
Close the extraction valve and open the drainage valve. The previously measured sample will drain out of the unit.
 
Flow pattern when draining excess sample or solvent
Open both the extraction and drainage valves simultaneously. All the fluid will drain out of the unit.
 
Complete dispersion, mixing and extraction
The extraction tank uses HORIBA’s specially designed agitator blades. Pushing the EXTRACT button initiates a powerful rotary dispersion and mixing action. To assure proper measurement of your oil sample, the extraction time can be preset in 10 second increments to any desired interval from 10 seconds to 10 minutes.
