Ph Tester - pH 100a

PH-100A – High Precision Digital pH Meter

PH-100A is a high-accuracy digital pH meter designed for reliable water quality testing across a wide range of applications. Built for precision and durability, it delivers fast, stable readings with automatic temperature compensation, making it suitable for hydroponics, aquaculture, pools, laboratories, and general water testing.

Each unit is individually tested and verified in New Zealand to ensure reliability and performance, helping eliminate the common issue of “dead on arrival” units found with lower-quality & imported alternatives.

Additional Information

All units are pre-calibrated before dispatch and supplied with sachets of storage solution. Designed for higher accuracy than most entry-level meters under $100, the PH-100A provides dependable performance for both hobby and professional users. These units also have upgraded battery capacity, now featuring 4x LR2032 for more operation time (vs the old outdated style of 3x LR44 batteries)

Note: Product colour may vary between white and off-white/cream due to manufacturing batches.
