KWS-300B Digital Conductivity Sensor
Standard Digital Conductivity Probe
Description
Introduction
The presents a new-generation four-electrode conductivity sensor developed with advanced international four-electrode technology. It features an RS485 digital interface, supports the MODBUS protocol, and adopts an environmentally friendly design. Compared with conventional two-electrode conductivity sensors, it offers higher measurement accuracy, a wider measuring range, and superior long-term stability.
The four-electrode conductivity sensor provides clear technical advantages. It effectively eliminates polarization effects during high-conductivity measurements and significantly reduces measurement errors caused by electrode contamination, ensuring reliable and accurate readings over extended operation.
Features
- Simultaneous output of conductivity, salinity, TDS, and temperature parameters
- Corrosion-resistant housing with IP68 waterproof rating for long-term underwater operation
- Built-in temperature sensor with automatic temperature compensation
