KaiNaFu Launches Digital pH/ORP Dual Sensor for Online Drinking Water Quality Monitoring

Shenzhen, China — KaiNaFu, a professional manufacturer of water quality monitoring instruments, has officially launched the KNF-101-2 digital pH/ORP dual sensor. This next-generation online probe is purpose-built to monitor pH, ORP, and temperature simultaneously in drinking water pipelines, delivering a compact, cost-effective solution for municipal water utilities and industrial water treatment plants.

The new sensor integrates digital circuitry directly inside the sensor body. This design allows a single device to continuously measure three critical water quality parameters at once, eliminating the need to install separate pH and ORP probes and reducing both installation complexity and total system cost.

As water safety regulations tighten worldwide, utilities increasingly require continuous online monitoring rather than periodic manual sampling. The KNF-101-2 addresses this demand by providing laboratory-grade accuracy in a rugged, field-ready package that can be deployed directly inside drinking water pipes or within a flow cell for easy maintenance and calibration.

Key Features

• Dual-parameter measurement — one sensor measures both pH and ORP simultaneously.
• Standard Modbus-RTU protocol — easy connection and seamless integration with PLCs, SCADA systems, and cloud platforms.
• Power isolation design — ensures a stable, interference-free signal output for reliable readings.
• IP68 protection grade — supports long-term underwater operation in harsh environments.
• RS-485 transmission interface — enables reliable long-distance data communication.

Technical Specifications

Additional specifications include a DC 9–27 V power supply, 0.5 W power consumption, black ABS shell material, dimensions of 198 mm × Φ32 mm, working pressure below 0.1 MPa, and an operating temperature range of -5 °C to 45 °C without freezing.

Applications

The pH ORP dual sensor is widely applicable for online monitoring of drinking water, surface water, groundwater, and sewage. Its flow cell installation support makes it especially suitable for drinking water pipes where continuous, real-time water quality monitoring is required.

Cloud Platform Integration

All KaiNaFu water quality equipment can connect to the Kainafu water quality monitoring cloud platform (DATAIO), which supports data reception, display, statistics, automatic analysis, storage, download, and release. Monitoring centers can view intuitive visual charts on desktop web, Apple and Android apps, and WeChat mini-programs.
