Nitrate Monitoring



Measure Nitrate Concentration in Water using LoRaWAN


Nitrate Sensor
LoRaWAN node
  • Continuous, in situ measurement of nitrate concentration in groundwater, surface water (rivers, lakes), and process industries. Designed for long-term, autonomous installations where a low-cost ISE (Ion Selective Electrode) nitrate sensor doesn’t work.
  • Uses a new and innovative optical sensor for limited spectrum UV absorption. Accurate measurement of low nitrate concentrations in the most remote locations without spending tens of thousands of dollars.
  • Measurement range 0 – 50 mg/L. Accuracy ±5% + 0.1 mg N/L. Resolution 0.1 mg/L. Get full specifications.
  • Fully self-contained device with solar power.
  • Set or change “over the air” how frequently data is measured- typically every 15 minutes or 1 hour.
  • Uses KotahiNet’s own LoRaWAN node. Available in all global LoRaWAN frequency bands.
  • Option for private LoRaWAN network and, coming soon, direct device to low earth satellite communication
  • Connect to our or your own data storage, processing and visualisation service. View readings or graphs online. Set high/low threshold levels for warnings.
  • Cost (in NZ Dollars, excluding GST if applicable): $8,250
