KWS-300A Digital Conductivity Sensor
4-Electrode High-Accuracy Conductivity Sensor
Description
Introduction
The introduces a new generation of four-electrode conductivity sensor, adopts international leading four-electrode technology, RS485 digital interface, supports MODBUS protocol, and environmentally friendly design. Compared with the traditional two-electrode conductivity sensor, it has higher accuracy, wider measurement range and excellent stability. The four-electrode conductivity sensor also has a unique advantage in quantity: one is to completely solve the polarization problem in high conductivity test; the other is to solve the problem of inaccurate reading caused by electrode contamination.
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
