The N900 series online digital ammonium nitrogen (NH4-N) sensor apply the ion selective electrode (ISE) method to measure the concentration of ammonia nitrogen. The N900 integrates ammonium ion selective electrode with the compensation of ion K+ potassium , pH and temperature. These parameters compensate the measurement value of ammonia nitrogen and showing multi-parameter measurement reading. The N900 is completed with standard digital signal output, integrating and networking with other equipment without controller.

The IUNI-21 dual channel analyzer is an effective option that can connect two digital ammonia nitrogen sensors at the same time to reduce the cost of transmitter and installation space:

  • Field mounted dual channel analyzer with datalogger
  • Connect two sensors at one time
  • 4-20mA output
  • Relay output
  • Communication, RS485 (Modbus)
  • LCD visual display
  • User friendly and attractive operating interface

Price is indicative, consisting of 1 x IUNI-21 Universal Transmitter and 1 x N900 Digital Ammonia Nitrogen Sensor.
