Digital pH Meter (PH-02) — Apex Labs

Product Summary

The Apex Labs Digital pH Meter (PH-02) is a compact digital water quality testing instrument designed for convenient and rapid measurement of pH. With a 0.00–14.00 pH measuring range, 0.01 pH resolution and automatic two-point calibration, this portable meter is suitable for routine water testing and laboratory applications.

Its pocket-sized design and easy-to-read digital display make it suitable for testing drinking water, swimming pools, spas, aquariums, RO systems, hydroponic solutions and educational laboratory samples. The digital readout eliminates the need to interpret colour charts or pH test strips when a numerical measurement is required.
