AI Hydro Sensor, for pH, EC, TDS and Water Temp Data Tracking

€179,00
incl. VAT, plus shipping costs
  • Sensor for comprehensive water quality monitoring: measures pH, EC (electrical conductivity), TDS (total dissolved solids) and temperature.
  • Monitors water values around the clock and enables automatic adjustments – no more manual checks.
  • Replaceable probes: only the worn sensor is replaced, which lowers maintenance costs.
  • Versatile: for grow irrigation, pools, aquariums and water treatment.
  • Part of the UIS™ platform (UIS: Universal Infinity System) and compatible with the CONTROLLER AI+.

Product Description

The Hydro Sensor was developed for direct use with the CONTROLLER AI+.

It automates the monitoring of pH, EC, TDS and temperature values that are important for healthy plant growth and provides the data for appropriate nutrient dosing. In irrigation systems with a water tank, it helps determine the right timing and amount of nutrients – saving water and supporting plant health and yields.

  • 4 valuespH, EC, TDS, temperature
  • IP-68Continuously submersible
  • ReplaceableProbes
  • 6 solutionsfor calibration included
  • 3.66 mCable length

Nutrient Management

Around the Clock

Continuous monitoring of water values with automatic adjustments via the CONTROLLER AI+.

Replaceable Probes

Only the worn sensor is replaced – reducing long-term maintenance costs.

Versatile Use

For grow irrigation, pools, aquariums and water treatment.
