THROUGH THE Cultivator's LENS Hands-On Evaluation

  • You are upgrading your sensing gear because you need consistent results without waiting for a 25°C calibration fix.
  • You are switching to this combo pen because you keep dropping your meter into tanks and need something that floats.

  • The dry storage electrode saves you from the messy liquid storage bottles that constantly leak in your gear bag.
  • The analogue EC calibration is a relief because it removes the pressure to find an exact temperature buffer.

  • Growers who switch to this unit say they finally stopped dealing with damaged sensors after accidental water submersions.
  • Users who previously struggled with calibration consistency report they get accurate readings on the first attempt now.

Aqua Master Tools P160 Pro Combo Pen

Needing an exact 25°C calibration solution before you can trust your meter is a hassle most growers don't have time for. The Aqua Master Tools P160 Pro solves that with an analogue EC calibration function that works regardless of solution temperature, plus a 2-point auto pH calibration, so getting an accurate pH, EC, PPM, TDS, or temperature reading never depends on lab-perfect conditions.

As the premium model in the lineup, the P160 Pro ships in a robust carrying case complete with pH 4.01, pH 7.00, and EC 1413 calibration solutions, so you're ready to calibrate right out of the box. A dry storage electrode means you don't need to keep it soaking in liquid between uses, and it's IP67 waterproof and buoyant enough to float, so an accidental drop into a tank costs you nothing.

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

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