Hanna HI98127 pH/Temp Meter

The Hanna HI98127 is a waterproof pocket-sized meter that simultaneously measures pH and temperature, offering ±0.1 pH accuracy with automatic temperature compensation (ATC) for reliable readings across varying water temperatures. The large, easy-to-read LCD display shows both measurements simultaneously, and the meter is rated IP67 waterproof, making it safe for direct aquarium use. Calibration is performed with standard buffer solutions (pH 4.01, 7.01, 10.01) using a two-point process for high accuracy. The replaceable pH electrode extends the lifespan of the device significantly, making it a cost-effective long-term investment. Ideal for freshwater, planted tanks, and monitoring water prior to water changes.
