THROUGH THE Cultivator's LENS Hands-On Evaluation

  • You are adding pH monitoring because your current strips leave you guessing at nutrient availability
  • You are choosing a waterproof meter because your previous devices failed after a minor splash in the reservoir

  • The buoyant design is a genuine lifesaver because it stays on the surface if you accidentally drop it in a tank
  • We suggest picking up a bottle of storage solution right away because it keeps the electrode sensing accurately

  • Users report they stopped buying replacement meters since they realized they could just swap the electrode
  • Growers say the clear calibration indicator helped them stop second guessing their liquid nutrient levels

Aqua Master Tools P50 Pro pH Temp Meter

Dropping a meter in the reservoir is a fast way to lose it — and an inaccurate pH reading is a fast way to stress a crop. The Aqua Master Tools P50 Pro solves both: it's IP67 waterproof and buoyant enough to float, while a 2-point auto calibration feature keeps every pH and temperature reading accurate across a wide range of liquids.

An ergonomic rubber back and a secured cap cord make the P50 Pro comfortable to hold and hard to misplace, while a replaceable electrode extends the meter's usable life well beyond a standard pen. It ships ready to use, batteries included.

For long-term accuracy, store the meter upright with KCl storage solution in the protective cover.
