KaiNaFu Technology proudly introduces the KNF-101-1 Digital Inline pH Sensor, a next-generation water quality monitoring solution purpose-built for drinking water pipeline networks. Combining high-precision electrochemical measurement with industrial-grade MODBUS RTU communication, this sensor sets a new benchmark for reliability in potable water monitoring applications.

1. Product Overview

The KNF-101-1 integrates advanced digital circuitry directly into the sensor body, delivering real-time pH and temperature readings via RS-485 interface using the standard MODBUS RTU protocol. Engineered for continuous inline deployment in municipal drinking water distribution systems, it ensures consistent water quality oversight without the complexity and maintenance burden of traditional analog probes.

2. Key Features

• Power Isolation Design – Galvanically isolated power circuitry eliminates signal interference, ensuring stable and accurate readings even in electrically noisy pipeline environments.
• Standard MODBUS RTU Protocol – Plug-and-play integration with existing SCADA and PLC systems. No proprietary converters or gateways required.
• Dual Output Flexibility – Simultaneous RS-485 digital output and 4-20mA analog output for maximum compatibility with both legacy and modern monitoring infrastructure.
• Ultra-Low Power Consumption – Operating at just 0.5W, the sensor is ideal for remote or solar-powered monitoring stations along extensive pipeline networks.
• Drinking Water Compliant – Materials and construction meet regulatory requirements for direct contact with potable water.

4. Cloud Monitoring Platform – DATAIO

The KNF-101-1 seamlessly connects to the DATAIO Water Quality Monitoring Cloud Platform, enabling centralized data reception, real-time visualization, automatic statistical analysis, historical storage, and remote downloads. Operators can monitor pH trends across entire drinking water distribution networks via desktop web browser, Apple/Android mobile apps, or WeChat mini programs — all from a single unified dashboard.

This cloud-native architecture empowers water utilities to move from reactive sampling to proactive, continuous quality assurance, dramatically reducing the risk of undetected pH excursions in public water supply systems.

5. Application: Drinking Water Pipeline Monitoring

The KNF-101-1 is engineered specifically for inline deployment in potable water distribution pipelines. With its robust RBMS installation system, low-pressure rating (<0.1 MPa), and drinking water-compliant materials, it is ideally suited for:

• Municipal drinking water treatment plant effluent monitoring
• Distribution network quality checkpoints
• Secondary water supply station monitoring
• Building water system compliance monitoring

6. Manufacturing Excellence

Manufactured in Shenzhen, China by KaiNaFu Technology, the KNF-101-1 is backed by CNAS-accredited quality assurance and rigorous factory calibration. Each sensor undergoes multi-point verification before shipment, ensuring out-of-the-box accuracy and long-term field reliability.
