Kainafu Launches Upgraded KNF-101PRO pH Measurement Sensor with Replaceable Probe for Industrial & Laboratory Use

Shenzhen, China — Kainafu Technology, a professional manufacturer of online water quality instruments, has officially released its upgraded KNF-101PRO pH measurement sensor, a next-generation digital sensor engineered for industrial laboratories, water treatment plants and automated process lines. Designed with replaceable probes for easy maintenance and complete OEM support, the new pH measurement sensor helps customers cut maintenance costs and downtime while keeping high-precision, stable pH measurement around the clock.

1. Product Overview

Developed from extensive on-site application experience, the KNF-101PRO pH measurement sensor has undergone multiple upgrades over the original design to make installation and maintenance simple and convenient. It supports both pipeline installation (optional Y-shaped three-way fitting with end-face seal) and submersible installation. In pipeline mode the sensor withstands a maximum pressure of 6 bar; in submersible mode it operates reliably at a water depth of 50 meters. A wide choice of pH-sensitive membranes and salt bridge forms is available, making the sensor suitable for an even broader range of application scenarios. The uniquely designed electrolyte filling port also enables operators to add electrolyte at a later stage, effectively extending the service life of the sensor.

2. Replaceable Probe Design & OEM Support

Maintenance is one of the biggest hidden costs in pH monitoring. The KNF-101PRO solves this with a replaceable detection probe that can be swapped quickly without replacing the whole instrument, minimizing downtime and reducing long-term ownership costs. As a manufacturer with strong R&D capability, Kainafu provides full OEM/ODM services, including customized probe types, cable lengths, output formats and private-label branding, so integrators and distributors can build their own pH measurement solutions with confidence.

3. Key Features

• Digital sensor with RS-485 output supporting standard MODBUS RTU protocol
• No reagents required — no pollution, more economical and environmentally friendly
• Simultaneous measurement of pH and temperature
• Single-point ceramic sand-core liquid junction with strong biological tolerance (other junction types optional)
• Multiple sensitive-film options for special application scenarios
• Independent electrolyte refill port for extended sensor lifetime
• IP68 protection; supports 6 bar pipeline pressure and 50 m submersion depth
