• 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.

Stable readout and a broad dynamic range assure accuracy and simplify analysis of oil components.

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 unit’s broad measurement range eliminates the need for troublesome range switching. As a result, the OCMA-310 is quick, easy to use, accurate, and reliable.

Manual control
The two valve system lets you make sure that your sample is measured properly. Inject your sample and press the extract button to initiate mixing 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 valve) allows you to drain the sample after it has been measured.

0-200 mg/l dynamic range
The OCMA-310’s pyro-electric 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.
