Online oil-in-water analyzer selection center
Compare two reagent-free UV-fluorescence analyzers by range, pressure, accuracy, sensor construction and water matrix.
OIWOil-in-water measurement
01
Select by oil type and the actual water matrix
UV-fluorescence response depends on petroleum composition and the water matrix. Selection must include minimum-to-peak concentration, pressure, material, fouling, cleaning, mounting and interfaces—not only maximum range.
02
Confirm these conditions before selection
Minimum to peak range
Provide minimum, normal, peak and alarm mg/L values.
Pressure and construction
Confirm pressure plus standard SUS316L or seawater titanium construction.
Cleaning and interfaces
Provide fouling, mounting, automatic-wiper, cable, 4–20 mA, relays and RS485 requirements.

Oil-in-water selection questions
How should I choose POIL-700 or POIL-800?+
Start with POIL-700 for 0–50 mg/L and lower-pressure environmental-water duty. Compare POIL-800 for 0–100 mg/L, higher pressure, industrial service or seawater construction.
Are reagents required?+
No. Both supplied sheets describe reagent-free direct continuous measurement by UV fluorescence.
