All-metal sensor housing for demanding industrial duty
Industrial and seawater analyzer · POIL-800
Wide-Range Online Oil-in-Water Analyzer
The wider-range, higher-pressure model for petroleum, chemical, power, industrial-wastewater and seawater monitoring, with standard SUS316L or titanium-alloy construction.
0–100 mg/L±5% or ±0.15 mg/L≤0.4 MPa
Model-specific values checked against the supplied sheet
POIL-700 and POIL-800 retain separate ranges, accuracy, pressure, construction and dimensions. The black FUNEL transmitter image provides consistent export-market presentation.

Recommended applications
Petroleum and chemical wastewater
Monitor oil-bearing process water and treated industrial discharge.
Power and industrial water
Track oil contamination in power and industrial water-treatment systems.
Seawater projects
Use the titanium-alloy configuration when the project requires seawater construction.
Environmental monitoring
Measure surface water, groundwater, drinking water and pollution-source discharge.

Selection questions
Does UV-fluorescence measurement require reagents?+
No. The supplied sheets describe direct continuous sensing of petroleum fluorescence in water.
What is the main difference between POIL-700 and POIL-800?+
POIL-700 is 0–50 mg/L, ≤0.1 MPa and Ø60 × 213 mm. POIL-800 is 0–100 mg/L, ≤0.4 MPa and Ø60 × 263 mm, with a titanium seawater option.
Can the website image be used as a technical drawing?+
No. It provides consistent public presentation. Dimensions, interfaces and accessories come from the datasheet and order confirmation.
