Water matrix and oil type
State surface water, groundwater, drinking water, seawater or industrial wastewater and identify the petroleum or oil type.
OIW · Online UV fluorescence
Select online oil-in-water measurement by range, water matrix and industrial duty
POIL-700 and POIL-800 both use reagent-free UV fluorescence for continuous measurement, with different ranges, accuracy, pressure ratings, materials and sensor dimensions.

01 · Start with the sample
Confirm oil type, water matrix and concentration span
UV-fluorescence response depends on petroleum composition and the water matrix, so selection cannot rely on maximum range alone. Pressure, material, fouling, cleaning and mounting must be confirmed together.
Minimum, normal and peak
Provide minimum, normal, peak and alarm mg/L—not a single design value.
Pressure, material and mounting
Confirm pressure, standard SUS316L or seawater titanium construction, immersion point and service access.
Cleaning and interfaces
Confirm fouling, automatic wiper, cable, 4–20 mA, relays, RS485, quantity and destination.

04 · Common questions
Confirm this information before an inquiry
How should I choose POIL-700 or POIL-800?+
Start with POIL-700 for 0–50 mg/L, lower-pressure and general environmental-water duty. Compare POIL-800 for 0–100 mg/L, higher pressure, industrial service or seawater construction.
Are reagents required?+
No. Both models use direct continuous measurement by UV fluorescence.
How do the pressure ratings differ?+
POIL-700 is rated to ≤0.1 MPa; POIL-800 is rated to ≤0.4 MPa.
Which outputs are available?+
Both models provide three 4–20 mA outputs, three relays and Modbus RS485.
