pH/ORP Pocket Tester - with Replaceable Electrode (Single Unit)

This compact, pocket-size meter delivers accurate, multi-parameter measurements of pH, ORP, and temperature. With 0.01 pH resolution and ±0.02 pH accuracy, it ensures precise readings, supported by a broad ORP range of -1000 to +1000 mV. 

Built to be durable and waterproof, this tester withstands tough environments without compromising performance. What's more the 3-point pH calibration and auto buffer recognition simplifies setup, while the Automatic Temperature Compensation (ATC) guarantees consistent results from 0–60°C.
