Kam OOD Optical Oil Detector User manual

Brand: Kam

Model: OOD Optical Oil Detector

Type: User manual

Kam OOD Optical Oil Detector is designed to detect the presence of hydrocarbons in water, providing continuous, real-time data with a variable range up to 0-5000 ppm. It offers unmatched simplicity and pinpoint accuracy in an in-line meter, allowing operators to monitor produced water, leak detection and wastewater streams for the presence of hydrocarbons in a variety of applications. The ideal solution for oil-in-water detection, the OOD allows operators to monitor produced water, leak detection and wastewater streams for the presence of hydrocarbons in a variety of applications, providing continuous, real-time data with a variable range up to 0-5000 ppm.
