Milwaukee PH55 PRO Waterproof Acidity and Temperature Meter with replaceable electrode

The Milwaukee PH55 PRO is a pH and water temperature meter with replaceable electrode.

Professional, portable and watertight pH meter with built-in thermometer and digital calibration. pH meter with large LCD display showing pH and temperature (°C or °F). The large display shows readings over an extended range from -2.0 to 16.0 pH and simultaneously displays the temperature from -5.0 to 60.0 °C. The Milwaukee pH55 has a stability indicator and a Hold function to freeze the display for easy and accurate data reading. The large screen also has graphical symbols to guide you through the procedures.

Temperature probe compensation for faster and more accurate measurement. Calibration is performed automatically in 1 or 2 point readings – standard and NIST solvation. Automatic switch-off saves battery power after non-use. The double electrode joint allows you to replace a new probe in a very quick and easy way! The modular design makes it easy to change the electrode and battery. Calibration fluids pH4.01 and pH7.01 are also included.

Measuring devices

Why are pH meters so important?

The pH value indicates how acidic / basic a liquid or soil is. For your plants to thrive, it is important to pay attention to the pH value of the soil and the irrigation water!

Most plants are most comfortable in a slightly acidic to slightly alkaline environment. This corresponds to a pH value of 6 to 7.5.

Choosing the right measuring device depends on factors such as the desired accuracy and your budget. Take a look at our selection and get an overview!
