Aqua Master Tools P110 Pro 2 Combo pen - pH, EC and temp meter
The P110 Pro2 is an upgraded version of Aqua Master Tools’ trusted handheld meter for accurate measurement of pH, EC (electrical conductivity), and temperature in liquids. Designed for professional use in horticulture, agriculture, hydroponics, and water management, this new model combines precision, durability, and usability in one compact device.
What’s new in the Pro2 version:
Powered by standard AAA batteries (replaces button cells)
Black display with high-contrast white characters for enhanced readability
Selectable precision: choose between 1 or 2 decimal points
30-day calibration reminder to ensure long-term accuracy
With both hardware and software improvements, the P110 Pro2 remains a reliable favorite among growers and technicians. Its IP67 waterproof housing is not only splash-proof but also floats – reducing the risk of accidental loss in tanks or basins.
The device is equipped with a large, backlit digital display with automatic temperature compensation (ATC) and an automatic shutdown (Auto-OFF) function. It has an intuitive interface and calibration options for each parameter.
The device features a dry-storage electrode, meaning it does not require storage in liquid. The replaceable 3-in-1 electrode (pH, EC, and temperature) extends the lifespan of the meter and allows for easy maintenance.
Whether you're managing nutrient solutions or monitoring water quality, the P110 Pro2 delivers accurate, stable, and fast measurements in a wide range of liquid environments.
