B-One PP-203 Handheld pH/mV Meter GonDo

B-One PP-203 Handheld pH/mV Meter – Compact Multi-Parameter Tester for pH, ORP, and Temperature with ATC

The B-One PP-203 Handheld pH/mV Meter GonDo is a versatile, portable instrument that combines the functions of a pH meter, mV (ORP/Redox potential) meter, and digital thermometer in a single, compact device. Built on the robust foundation of the PP-201, the PP-203 includes enhanced functionality such as automatic temperature compensation (ATC) and mV measurement up to ±1999, making it ideal for advanced laboratory and field testing.

Whether you’re testing water quality, conducting environmental field studies, or calibrating oxidation-reduction processes in industrial applications, the PP-203 provides high-accuracy results, a rugged splash-proof design, and user-friendly operation. The device supports 5-point calibration, has a switchable °C/°F display, and is powered by a 9V battery or AC adapter, making it a reliable choice for both mobile and bench-top applications.
