Product Description Features Adopt ion selective electrode (ISE) method Digital sensor, RS-485 output, support MODBUS No reagents, no pollution, environmentally friendly With self-cleaning brush, longer maintenance cycle Automatically compensat pH and temperatureNote: The ion electrode is only suitable for fresh water application scenarios, not for sea water SpecificationModelNH351Measuring PrincipleIon selective electrode (ISE) methodMeasuring RangeNH4-N: 0~1000mg/LAccuracyNH4-N: 5% of the measured value ± 0.2mg/L pH: 0.1pHResolutionNH4-N: 0.01mg/LCommunicationRS-485, MODBU-RTURelated MeasurementpH: 5.0~9.0pH (recommendation)Temperature Range0~45oC (does not freeze)Storage Temperature0~50oC (does not freeze)Working Pressure1 barProtection GradeIP68Shell MaterialPOMInstallationInvestment, 1 inch NPT pipe thread DimensionDiameter: 65mm Length: 275mmPrinciple:The sensor utilizes an ammonium ion-selective electrode (NH4+-ISE) to measure ammonia nitrogen (NH4+/NH3) in aqueous solutions. The ISE consists of a polymer membrane doped with a selective ionophore (e.g., nonactin or monactin), which generates a membrane potential proportional to the logarithmic concentration of ammonium ions (NH4+) via the Nernst equation.Application:
