Applications
Suitable for real-time oil-in-water monitoring in petroleum and chemical wastewater, power-industry water systems, industrial discharge outlets, surface water, groundwater, seawater and drinking-water source monitoring. The method is intended primarily for mineral-oil measurement rather than animal or vegetable oils.
Installation & Integration
Specify the water matrix, expected oil range, immersion or flow-cell arrangement, material requirement, cable length, power supply and control interface when requesting a quotation. For saline or corrosive service, request the titanium version where appropriate.
