Nutrient Monitoring: Ammonium, Chloride, and Nitrate ISE Sensors

Designed for use in a variety of applications, the Aqua TROLL 600 Multiparameter Sonde from In-Situ provides accurate water quality data in natural water, surface water, groundwater, produced water, and aquaculture. Additionally, the Aqua TROLL 600 Ammonium, Chloride, and Nitrate Sensors are ideal for any application where real-time data for nutrient monitoring and/or early detection of contamination is useful in applications such as influent and effluent monitoring for source, drinking and waste water, sediment run off and nutrient contamination  from storm water, nutrient contamination and long term testing for groundwater, as well as further applications in aquaculture, agriculture and mining. 

Aqua TROLL offers a superb level of sensor stability. Traditional ISE sensors typically drift within hours to days, however In-Situ sensors are showing minimal drift even after more than a month of deployment. Gone are the days of weekly or even daily calibrations, In-Situ are recommending a monthly 2-point calibration for these sensors. There’s no iso-thermal calibration required either. The ammonium sensor will automatically derive ammonia and total ammonia when used in conjunction with a pH/ORP sensor.

In-Situ’s sensor range is significantly wider than others on the market. In addition, the ammonium and nitrate sensors are rated to a depth of 25m, and the Chloride Sensor can be used to the current pressure range of the Aqua TROLL 600 (350 psi).
