Apera PC850 Portable pH/Conductivity Meter Kit

Overview

The Apera PC850 Portable pH/Conductivity Meter Kit is a professional multi-parameter water quality meter designed for accurate field and laboratory measurements of pH, conductivity, TDS, ORP (optional), and temperature. Engineered with a rugged IP57 waterproof housing, the PC850 is ideal for environmental monitoring, water treatment, aquaculture, industrial process control, education, and laboratory testing.

The meter supports simultaneous connection of up to three electrodes, allowing efficient measurement of multiple parameters without repeatedly changing sensors. Equipped with the proprietary Apera 201T-F pH/Temperature Electrode and 2301T-S Conductivity/Temperature Electrode, the PC850 delivers fast response, excellent stability, and high measurement accuracy.

Featuring automatic multi-point calibration, customizable measurement parameters, automatic temperature compensation (ATC), and a large LCD display with stability indicators, the PC850 provides reliable results in both field and laboratory environments. The foldable stand also enables convenient benchtop operation.
