  UV Analysis Eliminates Reagents, Sampling, and Sample Conditioning

  Using advanced ultraviolet （UV） absorption technology, Hach NITRATAX sc UV Nitrate Sensors offer unprecedented simplicity, accuracy, and economy in nitrate analysis. By continuously measuring the UV light absorbed by nitrates, NITRATAX sc sensors eliminate the need for reagents, sample conditioning, and frequent calibrations.

  UV Absorption Method - Proven, Continuous, Precise

  NITRATAX sc sensors rely on the principle that molecular bonds absorb ultraviolet （UV） light. In this case, nitrate （NO3） and nitrite （NO2） absorb UV light. As the concentration of nitrate or nitrite increases, UV absorption also increases. A built-in photometer measures the primary beam, while a second beam of UV light provides a reference standard and corrects for interference caused by turbidity and organic matter. Results are reported on the controller unit's alphanumeric display in mg/L of nitrate （NO3） or nitratenitrogen （NO3-N）.

  Choice of Three Models

  NITRATAX plus sc Process sensor for continuous measurement in drinking water, wastewater, or activated sludge. Turbidity compensation using reference measurement. NITRATAX eco sc low cost sensor for measurement, especially for sewage treatment plants with intermittent aeration technology. Turbidity compensation using reference measurement. NITRATAX clear sc Process sensor for continuous measurement in clean water such as drinking water or wastewater effluent.

  Self-Cleaning Sensor

  With the sensor submerged in the sample stream, the detector windows are automatically cleaned by a built-in wiper that eliminate surface films or particles that can diminish accuracy.

  Optional Bypass Panel

  An optional Bypass Panel or flow-through sample cell is available for clean water applications when direct immersion inOptional Bypass Panel a sample stream is impractical. The Bypass Panel uses the same probes as the immersion sensors for greater flexibility.
