Introduction
KWS700 digital pH sensor adopts industrial online electrode, built-in temperature sensor, can automatically temperature compensation, suitable for industrial sewage outlets, general rivers, manholes and other online long-term monitoring environments. The sensor adopts RS485 output and supports Modbus, which can realize networking and system integration without a controller.
Feature
- Signal output: RS-485 (Modbus/RTU protocol).
- 4-20mA output easy to installation to PLC/DCS system.
- Convenient connection to third-party equipment such as PLC, DCS, industrial control computer, general controller, paperless recording instrument or touch screen.
- Using high-performance industrial online electrodes, can work stably for a long time
- Built-in temperature sensor, automatic temperature compensation
