K Sensor RS485

This industrial K sensor RS485 is an in-situ digital potassium ion sensor using ion-selective electrode (ISE) technology, with built-in transmitter and RS485 Modbus-RTU output. It provides real-time K⁺ measurement, automatic temperature compensation, self-calibration and IP68 waterproofing, widely used in water quality monitoring, aquaculture, hydroponics and industrial process water.

K Sensor RS485 This digital potassium (K⁺) sensor integrates a high-performance potassium ion-selective electrode (ISE), reference system, temperature sensor and digital signal conditioning module. It directly outputs calibrated K⁺ concentration data via RS485 Modbus-RTU, no separate transmitter required.

• ISE sensing technology: high selectivity for K⁺ ions, fast response
• Double-junction reference: anti-poisoning, stable in complex water matrices
• Automatic temperature compensation (ATC): 0–50°C
• Digital RS485 Modbus-RTU: long-distance transmission, strong anti-interference
• IP68 submersible design: for in-situ immersion/pipeline installation
• Supports 1/2-point calibration, data logging and self-diagnosis
• Housing: 316L stainless steel / PPS, standard 3/4" NPT mounting thread

K Sensor RS485 is an industrial-grade digital potassium ion (K⁺) sensor based on ion-selective electrode (ISE) technology, designed for in-situ online measurement of potassium ion concentration in surface water, drinking water, industrial wastewater and aquaculture water.

This digital potassium probe adopts standard RS485 interface and MODBUS-RTU communication protocol, supporting bidirectional data transmission and seamless connection with PLC, DCS, RTU and water quality monitoring platforms. Isolated power supply and isolated output design effectively improve electrical safety and anti-interference ability, ensuring stable measurement in complex industrial environments.

The sensor integrates automatic temperature compensation to ensure high accuracy under varying temperatures. It supports one/two-point automatic calibration, and the internal memory retains calibration data and parameters during power failure, avoiding repeated calibration. Built-in protection circuit enhances stability and service life.

With IP68 waterproof rating, corrosion-resistant PPS housing and standard 3/4-inch threads, the sensor can be installed quickly and operated submerged for a long time. It is widely used in environmental monitoring, water plant, aquaculture, industrial process water and other scenarios requiring online potassium ion detection.
