Kainafu Launches KNF-101PRO pH Sensor with Built-in Temperature Compensation for Precision Industrial Monitoring

Accurate pH measurement is the backbone of modern water treatment, laboratory analysis, and industrial process control. However, pH readings are highly sensitive to temperature changes — a factor that can quietly distort results and compromise process quality. Kainafu's newly upgraded KNF-101PRO industrial pH sensor directly addresses this challenge with integrated pH sensor temperature compensation, delivering stable, reliable readings across a wide operating range.

Why pH Sensor Temperature Compensation Matters

The electrochemical response of a pH electrode changes with temperature. Without compensation, a shift of just a few degrees can introduce measurable error into the output. The KNF-101PRO measures both pH and temperature simultaneously, enabling automatic correction and ensuring that operators always receive accurate, temperature-adjusted values. This makes it ideal for environments where process temperatures fluctuate throughout the day.

Built for Industrial and Laboratory Environments

Designed around extensive on-site application experience, the KNF-101PRO supports both pipeline installation (withstand up to 6 bar pressure) and submersible installation (reliable at depths up to 50 meters). Its IP68 enclosure protection, single-point ceramic sand core liquid junction, and corrosion-resistant materials ensure dependable performance in demanding conditions.

Key Features

• Digital sensor with RS-485 output and standard Modbus RTU protocol (0x03, 0x06, 0x10)
• Simultaneous pH and temperature measurement with automatic temperature compensation
• Replaceable probe design for easy maintenance and extended service life
• Reagent-free and pollution-free operation — economical and environmentally friendly
• Multiple sensitive membranes and salt bridge options for specialized applications
• Independent electrolyte filling port for convenient refilling
• IP68 protection, up to 6 bar pipe pressure and 50 m submersion depth
• Wide 5–30 VDC power supply with ultra-low power consumption (<10 mA @12 VDC)
