Kainafu High Accuracy pH Sensor: ±0.02 pH Precision for Reliable Water Quality Monitoring

In water quality monitoring, every decimal point matters. A pH reading that drifts by even 0.1 can change a compliance decision, a chemical dosing calculation, or a product-quality verdict. This is why laboratories, water utilities, and industrial plants worldwide depend on a high accuracy pH sensor to make confident, data-driven decisions every single day.

Shenzhen Kainafu Technology Co., Ltd. designs and manufactures a complete series of high accuracy pH sensors built for drinking water, wastewater, tap water, aquaculture, and industrial laboratory applications. With measurement precision down to ±0.02 pH and a resolution of 0.01 pH, Kainafu pH probes deliver laboratory-grade stability in demanding online environments.

Product Series Overview

The Kainafu high accuracy pH sensor series combines proven glass-electrode technology with modern digital electronics. Every sensor outputs a stable RS-485 Modbus RTU signal, allowing direct integration into SCADA, PLC, and IoT water-monitoring platforms without extra signal conditioners.

  • KNF-101PRO — replaceable-probe pH sensor for industrial laboratories, 0.02 pH precision
  • KNF-101-1 — digital inline pH sensor for potable water pipes, low-maintenance and drinking-water compliant
  • KNF-101-2 — PH/ORP dual sensor for drinking water pipes with flow-cell installation
  • KNF-101A PRO — RS-485 pH/ORP probe for water supply networks with replaceable probes
  • QDA-01 — special flow cell for disinfectant transmission detection electrodes

Key Specifications
