Online ammonia nitrogen analyzer selection center
Compare two integrated ion-selective NH₄-N analyzers by compensation requirement, sensor size, installation and system interfaces.
NH₄-NAmmonia nitrogen measurement
01
Select for the actual water matrix and ion compensation
Ion-selective ammonia measurement depends on the water matrix, pH, temperature and interfering ions. Selection must include the process point, minimum-to-peak NH₄-N, potassium conditions, mounting, cable and control interfaces—not only maximum range.
02
Confirm these conditions before selection
Minimum to peak NH₄-N
Provide minimum, normal, peak and alarm values within the documented 0.1–3000 mg/L range.
pH, temperature and potassium
Confirm pH, temperature, potassium interference and whether optional K⁺ measurement is required.
Mounting and interfaces
Confirm installation space, cable, power, 4–20 mA, relays, RS485, quantity and destination.

Ammonia nitrogen selection questions
How should I choose PINH3-900 or PINH3-500?+
Both cover NH₄-N 0.1–3000 mg/L. Compare PINH3-900 when optional K⁺ measurement is required; compare PINH3-500 when a smaller probe is preferred.
Do both models include pH and temperature measurement?+
Yes. Both supplied sheets document pH 5–10 and 0–40°C as part of the integrated ammonia measurement and compensation.
