THROUGH THE Cultivator's LENS Product Evaluation

  • You are checking nutrient concentration because losing track of it is one of the fastest ways to underfeed your crop.
  • You are testing liquids frequently because an ergonomic rubber back keeps the meter comfortable to hold in your hand.

  • The 1-point auto calibration feature calibrates quickly at 1.4 EC for consistently accurate readings.
  • The electrode is replaceable, which extends the usable lifetime of the meter beyond a standard pen.
  • The housing is IP67 waterproof and buoyant enough to float if accidentally dropped into your reservoir.

  • Growers working around nutrient tanks say they stopped worrying about losing devices after dropping a buoyant meter into the reservoir
  • Users managing regular feeding schedules report that storing the meter upright with KCl storage solution keeps readings accurate long term

Aqua Master Tools E50 Pro EC Temp Meter

Losing track of nutrient concentration is one of the fastest ways to under- or overfeed a crop, and a meter you're afraid to dip into a tank doesn't help. The Aqua Master Tools E50 Pro solves both problems: it's IP67 waterproof and buoyant enough to float, while a 1-point auto calibration feature keeps EC and temperature readings accurate. Users seeking similar precision in a dedicated conductivity format might also consider the Aqua Master Tools E60 Pro Conductivity Meter.

An ergonomic rubber back and a secured cap cord make the E50 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.
