Aqua Master Tools Combo Pen P110 Pro2

Aqua Master Tools P110 Pro2 Combo Pen for pH, EC and temperature

The Aqua Master Tools P110 Pro2 Combo Pen lets you check three important nutrient-solution parameters with a single handheld meter: pH, electrical conductivity (EC) and temperature. It is suitable for indoor and outdoor growers who regularly monitor irrigation water and liquid plant nutrition. The Pro2 version combines straightforward operation with a robust waterproof body and a replaceable electrode.

Check three key parameters in your nutrient solution

The P110 Pro2 covers a pH measurement range of 0.00 to 14.00 and an EC range of 0.00 to 19.99 mS/cm. It also measures temperatures from 0 to 50 °C. Automatic temperature compensation accounts for the influence of temperature during measurement. The controls let you switch between pH and EC as well as Celsius and Fahrenheit. For other options, Growmart also offers dedicated pH meters and EC meters.

Pro2 display and built-in calibration reminder

The Pro2 version uses a black display with white characters for clear readability. pH and EC readings can be shown with either one or two decimal places, depending on the level of display detail you prefer. A calibration indicator appears after successful calibration and disappears after 30 days, providing a straightforward reminder that recalibration is due. The meter also switches itself off automatically after eight minutes of inactivity.

Waterproof, floating and easy to maintain

The housing is waterproof to IP67 and the pen floats if it is accidentally dropped into a reservoir. Its electrode is replaceable and designed for dry storage, so it does not need to remain in storage solution between uses. Before first use, the electrode should be soaked in tap water for at least twelve hours. After measuring, simply rinse the electrode with water before putting the meter away.

pH and EC calibration

For pH measurement, the P110 Pro2 supports automatic two-point calibration using pH 7.00 and pH 4.01 solutions. EC calibration is carried out manually by setting the value of the chosen EC calibration solution with the meter controls. This allows the instrument to be recalibrated routinely and prepared for accurate use again after replacing the electrode.
