High-Accuracy pH Measurement

The digital pH pen provides readings across the full 0.00–14.00 pH range with ±0.01 pH accuracy. Automatic temperature compensation helps maintain consistent measurements when testing solutions at different temperatures.

Automatic Calibration

The meter supports 1-, 2- and 3-point automatic calibration with intelligent buffer recognition and automatic stability checking. It is compatible with both NIST and USA calibration standards for flexible setup.

• NIST calibration points: pH 4.01, 6.86 and 9.18
• USA calibration points: pH 4.00, 7.00 and 10.01

Replaceable Probe

The interchangeable electrode allows the probe to be replaced when required without replacing the complete meter. This helps extend the useful life of the tester while maintaining dependable measurement performance.

IP67 Waterproof Design

An IP67-rated housing helps protect the meter against water and dust during everyday use. The protective cap includes a moist sponge to help maintain the electrode in suitable condition between measurements.

Convenient Everyday Testing

A backlit LCD makes readings easier to view in different lighting conditions, while automatic and manual hold functions allow measurements to be retained on screen after the meter is removed from the solution. Adjustable automatic shut-off also helps conserve battery life.
