Additional Information
Precise nutrient balance is vital for healthy crops, the Automatic Online Multi-Ion Nutrients Analyzer from NT Sensors measures seven key ions—calcium, chloride, sodium, potassium, ammonium, nitrate, and magnesium—in real-time, and without reagents.
It uses seven dedicated ISE (Ion-Selective Electrode) sensors to deliver accurate, drift-free readings for each ion. Subsequently, the unit runs automatic calibration, self-cleaning, and data transmission via Modbus or Webserver, so you always have live insights. Features an IP66-rated enclosure which withstands dust, spray, and temperature swings in greenhouses or field installations.
Plug-and-play analyzer reduces manual checks and prevents nutrient imbalances that stunt growth. Finally, seamless integration with SCADA/PLC systems lets you automate nutrient dosing, boost yield, and cut waste—effortlessly and continuously.

Measurement performance depends on the selected electrodes, sample composition, calibration standards, and operating conditions. A pressure reducer is required when the sample pressure exceeds the analyzer’s permitted inlet pressure. Specifications are subject to change.
Multi-Ion Nutrient Monitoring Applications
Simultaneous nutrient measurement helps growers, researchers, and water-management professionals identify imbalances, improve dosing, and make informed operating decisions.
Hydroponics & Aquaponics
Monitor essential ions in recirculating water to maintain nutrient balance and support consistent growing conditions.
Fertigation Systems
Track nutrient concentrations in greenhouse and open-field irrigation systems to support controlled fertilizer application.

What is an AMIC Multi-Ion Analyzer?
A multi-ion analyzer is an advanced water quality monitoring system designed to measure multiple dissolved ions simultaneously in real time. Using ion-selective electrode (ISE) technology, these analyzers eliminate the need for time-consuming laboratory testing and provide continuous, accurate data directly from the field or process line. This makes it an ideal solution for applications requiring fast, data-driven decision-making.
