Nitrate Analyzer and Control System

RealTech Controls offers two types of analyzers / controllers for monitoring and controlling Nitrate in industrial environments. The Nitrate Analyzer is designed to monitor the nitrification process directly in a wastewater treatment plant’s aeration basin or clarifier unit.

  • The Model ETX Nitrate Analyzer uses a HYDRA®-DS combination electrode that simplifies nitrogen (nutrients) and Ammonium measurements.  Its advanced sensor uses ISE technology to measure the concentration of dissolved nitrate as nitrogen (NO3-N) in water, and features a self-compensating design, where the unit automatically eliminates chloride ion interference, for high accuracy and reliability. An optional pH or NH4+ electrode is also available in the HYDRA®- NO3 sensor. While not required for the measurement an optional pH or Ammonium electrode can provide valuable information about the process. Temperature is measured and used to compensate each of the measurements.

  • The Model CA6 Nitrate Analyzer incorporates UV light technology for accurate, low range measurements of Nitrate in water. Nitrate is absorbs UV light in the range of range of 190-240 nm, therefore reagents are not necessary making this system cost effective and maintenance friendly.
