Who This Is For

  • Growers managing multiple nutrient reservoirs who struggle to manually track fluctuating pH and EC levels daily
  • Facility managers who need automated, round-the-clock water quality alerts to prevent crop nutrient lockout

What We Found

  • The 24-inch coaxial sensor cables provide enough slack to place the monitor in a convenient spot away from the basin.
  • We tell growers the programmable alert system saves them from having to check the screen during every tank rotation.

What Users Say

  • Users who set custom threshold alarms say they caught faulty dosing pumps before nutrient burn affected their batch.
  • Operations staff who utilized the memory storage report they identified trends in water uptake across growth stages.
