Product Details
KWS-206 Online NH4-N Ammonia Nitrogen Sensor With pH And
Temperature Compensation
Introduction
The Kacise KWS-206 integrated online ammonia nitrogen sensor is
fabricated using a PVC membrane-based ammonium ion selective
electrode for testing ammonium ion content in water with
temperature compensation to ensure fast, simple, accurate and
economical testing.
Feature
- 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 ammonium 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 grade.
