The Aqua TROLL nutrient sensors are ideal for any application where real-time data for nutrient monitoring and/or early detection of contamination is useful, including:

  • Agriculture and irrigation – monitor drainage and runoff
  • Source water, drinking water, and wastewater – influent and effluent monitoring
  • Stormwater – sediment runoff and nutrient contamination
  • Mining – mine water management and nutrient contamination monitoring
  • Groundwater – nutrient contamination and long-term testing
  • Aquaculture – pond, recirculation, farming, and wastewater monitoring

Aqua TROLL Ammonium ISE Sensor: 

The In-Situ Ammonium Sensor measures ammonium levels in natural water, surface water, groundwater, produced water and aquaculture applications. The Ammonium Sensor will automatically derive ammonia and total ammonia when used in conjunction with the pH/ORP sensor.

Sensor Overview:

  • Ion Selective Electrode (Membrane)
  • Range: 0 – 10,000 mg/L as N
  • Accuracy: ±10% or ± 2mg/L, whichever is greater
  • Rated to 25m (70ft) depth
  • Refillable reference junction
  • Derived parameters (requires pH and temperature)
  • Unionized Ammonia
  • Total Ammonia

Aqua TROLL Chloride ISE Sensor: 

The In-Situ chloride sensor measures chloride levels in fresh and salt water, groundwater, produced water and aquaculture applications.

Sensor Overview:

  • Ion Selective Electrode (Solid State)
  • Std. Methods 4500-Cl D
  • Range: 0 – 150,000 mg/L as Cl
  • Accuracy: ±10% or ± 2mg/L, whichever is greater
  • Rated to 200m (650ft) depth
  • Refillable reference junction (existing pH sensor reference)

Aqua TROLL Nitrate ISE Sensor: 

The In-Situ nitrate sensor measures nitrate levels in natural water, surface water, groundwater, produced water and aquaculture applications.

Sensor Overview:

  • Ion Selective Electrode (Membrane)
  • Std. Methods 4500-NO3 D
  • Range: 0 – 40,000 mg/L as N
  • Accuracy: ±10% or ± 2mg/L, whichever is greater
  • Rated to 25m (70ft) depth
  • Refillable reference junction
