NO₃-NNitrate nitrogen measurement
01
Select range and optical path for the actual water
PUVNO3-900 measures nitrate nitrogen by 210 nm UV spectral absorption without chemical reagents. Selection must include the expected range, 1 mm or 2 mm optical path, turbidity, solids, fouling, cleaning, pressure and mounting conditions.
02
Confirm these conditions before selection
Water matrix
State drinking water, surface water, industrial process water or wastewater plus turbidity and solids.
Mounting and cleaning
Confirm pressure, immersion position, automatic cleaning and maintenance access.
Interfaces and delivery
Confirm cable, power, 4–20 mA, relays, RS485, quantity and destination.

Nitrate selection questions
What is the difference between the two optical paths?+
The supplied sheet states 0.1–100.0 mg/L for the 1 mm path and 0.1–50.0 mg/L for the 2 mm path.
Are reagents required?+
No. PUVNO3-900 uses direct-immersion 210 nm UV spectral absorption without chemical reagents.
