KWS-270 Online Nitrate Nitrogen Sensor
Introduction
The KWS-270 integrated online nitrate nitrogen sensor is made of a PVC membrane-based nitrate ion selective electrode. It is used to test the nitrate ion content in the water with temperature compensation to ensure that the test is fast, simple, accurate and economical. This user manual introduces the technical parameters, maintenance and communication protocol of the nitrate nitrogen sensor in detail.
Feature
- Signal output: RS-485 bus, Modbus/RTU protocol, easy to connect to third-party equipment such as PLC, DCS, industrial control computer, general controller, paperless recording instrument or touch screen.
- The patented nitrate ion electrode, the internal reference liquid seeps out from the microporous salt bridge very slowly under a pressure of at least 100KPa (1Bar). Such a reference system is very stable, and the electrode life is longer than that of ordinary industrial electrodes.
- The membrane cap can be replaced, reducing costs
- Easy to install: 3/4″ NPT pipe thread is convenient for sinking installation or installation in pipelines and tanks.
