KWS-280 Online high performance-price ratio nitrite in water sensor
Introduction
The KWS-280 integrated online nitrite sensor utilizes a nitrite ion-selective electrode based on a PVC membrane. It is used to measure nitrite ion levels in water and features temperature compensation, ensuring fast, simple, accurate, and economical testing. This user manual provides detailed information on the sensor’s technical specifications, operation, maintenance, and communication protocols.
Feature
- Signal output: RS-485 bus and Modbus RTU protocols facilitate connection to third-party devices such as PLCs, DCSs, industrial control computers, general-purpose controllers, paperless recorders, or touch screens.
- The patented nitrate ion electrode features an internal reference solution that very slowly seeps out of the microporous salt bridge at a pressure of at least 100 kPa (1 bar). This highly stable reference system extends the electrode life compared to conventional industrial electrodes.
- Easy installation: 3/4 NPT threads facilitate drop-in installation or installation in pipes and tanks.
