pH Meters are indispensable tools in a grow room environment. The ESSENTIALS pH Meters are known for their reliability and ability to store up to 10 previous readings, enabling growers to effectively monitor their pH levels and respond swiftly to any irregularities.

Key Features:

  • Memory Storage: Holds up to 10 pH readings, making it easier to track changes over time.
  • Water Resistant: The meter is designed to float and remain undamaged if accidentally dropped in liquid, provided it is quickly retrieved and dried.
  • Shock Resistant: Robust enough to withstand accidental drops without sustaining damage.
  • Low Battery Alert: Alerts users when only two hours of running time remain, ensuring timely battery replacement.
  • Auto Shut-Off: Saves energy by turning the meter off when not in use.
  • Simple Calibration: Calibration is straightforward with VitaLink Essentials Calibration Fluid. Just immerse the probe in the solution and press the 'CAL' button until 'CAL' appears on the display.


  • Memory Function: This feature allows growers to log pH changes and correlate these with potential adjustments needed in their nutrient solutions or water quality.
  • Durability: Water and shock resistance ensure that the meter can endure typical grow room accidents without failure.
  • Maintenance Alerts: The low battery alert and energy-saving shut-off feature keep the meter ready for use and extend its operational lifespan.
  • Calibration Ease: The meter eliminates the hassle often associated with calibration, providing quick and accurate calibration to ensure consistent, reliable readings.

These attributes make the ESSENTIALS pH Meters a vital asset for maintaining optimal conditions in grow rooms, helping growers achieve the best possible results from their plants.
