Organic Pollutant Monitor
The OPSA-150 is a organic pollutant monitor that uses HORIBA's proprietary Rotary Cell Length Modulation, a measuring technique incorporating 25 years of expertise. The unit can be used as an organic pollutant monitor at drainage systems for determining compliance with COD monitoring regulations, for monitoring quality of water measuring levels of organic matter at water supply intakes, and as an organic monitor on process lines (phenol meter).
*Pole mount, outdoor cover, and analysis panel are available as options.

Zero drift correction is perfomed in every cycle of measurement. This correction can eliminate the effect of any interference on cells.
Cell length modulation provides readings from multiple measurements, making available results from various cell lengths. This allows the single device to make measurements on a large range of concentrations from as low as 0 to 0.1 Abs, up to 0 to 5.0 Abs.

Control of the OPSA-150 is operated via the intuitively designed touch panel. An interactive setup screen eliminates any doubts that a user may have while operating the unit. The Converted COD and TURB Display allow readings to be confirmed on site.
Internal data memory provides data strage for one year in case of one measuring value per hour. A CompactFlash® card can be used to allow easy transfer of data to a PC.
The cell is cleaned continuously by the wiper to eliminate any interference in the measurement light path. Therefore, errors in readings from dirty cells, or differences in results before and after cleaning are not evident.
The sample error alarm provided as an option on the previous OPSA120 is now a standard feature.
The mimimum accuracy of analysis ability has been increased to 0.0001 Abs, a ten-fold increase over the previous OPSA-120 unit. Measurements can be made on concentrations as low as 0 to 0.1 Abs.
