Take complete control over your nutrient solutions and water quality with the VIVOSUN Digital pH & TDS Meter Combo Water Test Kit. Perfect for hydroponics, indoor grow rooms, home aquariums, swimming pools, and reverse osmosis (RO) filtration systems, this handheld testing duo provides lab-grade precision within seconds.
Featuring ultra-sensitive electrodes and built-in Automatic Temperature Compensation (ATC), both pens adjust automatically to your water temperature. This eliminates tracking errors and ensures perfectly stable, accurate readings whether you are measuring ice-cold reservoir top-ups or warm nutrient brews.
Key Benefits

  • Ultra-Precise & Rapid Readings: Highly sensitive probes deliver instant data, helping you prevent nutrient lockout, root burn, and overfeeding before it hurts your crops.
  • One-Touch Auto Calibration: The pH pen features smart multi-point calibration that pairs perfectly with the included powder buffer packets for seamless maintenance.
  • Data-Hold & Backlit Displays: Crystal-clear green backlit LCD screens allow effortless reading under harsh grow lights or inside dim tents. Use the manual "Hold" function to freeze readings for your logbook.
