Aqua Master Tools P50 PRO 2.0, pH metre and thermometer

Product detailed description

Aqua Master Tools P50 PRO 2.0 combines a pH metre and thermometer in a pocket-sized device for checking irrigation water and nutrient solution. It helps verify pH before watering; always adjust the target value to the growing medium and nutrition.

What the P50 PRO 2.0 measures

• pH in the range 0.0 to 14.0 pH, with optional resolution of 0.1 or 0.01 pH,
• solution temperature in the range 0 to 50 °C.

Automatic temperature compensation works in the range 0 to 50 °C. The device has IP67 protection, floats on the surface and switches off automatically after eight minutes of inactivity.

Calibration and care

From the factory, the P50 PRO 2.0 comes calibrated, so you can read the first value straight after unpacking and you do not need to adjust anything. The pH metre has automatic two-point calibration at pH 4.0 and pH 7.0. Use pH 4 calibration solution and pH 7 calibration solution. Before first use, soak the electrode in tap water for at least 12 hours. The electrode of this model is intended for dry storage.

When to choose the P50 PRO 2.0

It is suitable when you are dealing with pH separately. If you need to check the electrical conductivity of the solution at the same time, choose a combined pH and EC metre. If worn, the probe can be replaced with a spare electrode for the P50 PRO.

Frequently asked question

Does the P50 need to be calibrated before every measurement?

No. Calibrate according to the condition of the electrode and how regularly you use it; for accurate measurement, use fresh pH 4 and pH 7 calibration solutions.
