Description
Overview
GAOTek nitro sense, an integrated online nitrate sensor for water quality monitoring is fabricated using a PVC membrane-based nitrate ion selective electrode for testing nitrate ion content in water with temperature compensation to ensure fast, simple, accurate and economical testing. The technical parameters, maintenance and communication protocols of the nitrate nitrogen sensor are described in detail in this user manual.
Features
- Signal output: RS-485 bus, Modbus/RTU protocol, convenient to connect to PLC, DCS, industrial control computer, general controller, paperless recording instrument or touch screen and other third-party equipment.
- The patented nitrate ion probe, the internal reference solution oozes extremely slowly from the microporous salt bridge at a pressure of at least 100 KPa (1 Bar). Such a reference system is very stable and has a longer electrode life than conventional industrial electrodes.
- Easy to install.
- 3/4 NPT thread (pipe thread) for easy submersible installation or installation in pipes and tanks.
- IP68 protection level.
