HORIBA Organic pollutant monitor OPSA-150

Organic pollutant monitor

OPSA-150

Long-term stable and high-precision measurements are achieved through our unique rotary cell length modulation method.

An organic pollutant monitor that applies HORIBA's proven and proprietary rotary cell length modulation method which has been developed over many years.  Suitable for use in monitoring organic pollutants at discharge points under the Total Pollutant Load Control System (TPLCS), organic matter measurement at water intake points for monitoring water quality, and monitoring organic substances in process lines (such as phenol meters).
