Kacise KAN601 Online Ammonia Nitrogen Sensor
Application Environment
KAN601 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. The
technical parameters, maintenance, and communication protocols of
the ammonia nitrogen sensor are described in detail in this user
manual.
- 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.
- In 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 level.

Dimensional Drawing
Tip: Measuring principle of the spectral on-line sensors for nitrate,
nitrite, and COD
The spectral measurement of nitrate and nitrite by kacise is based
on the principle of an absorption measurement; nitrate and nitrite
ions absorb light in the UV range.
The absorption measurement of 256 wavelengths over a wide
wavelength range is the so-called absorption spectrum.
From the high information content of the measured spectrum, the
measured values are calculated using evaluation models. The
evaluation models are based on methods and characteristics, which
were obtained from a variety of measurements and long-term
analyses. By using the entire information content of the spectrum,
it is possible to determine the parameters, several parameters at a
time and simultaneously eliminate cross-sensitivities of individual
parameters and interference effects such as turbidity.
• By using UV-VIS sensors (wavelength range of 200 – 720nm),
nitrate and carbon parameters (COD, BOD, TOC, SAC) and TSS can be
measured.
• In order to distinguish nitrate and nitrite, UV sensors
(wavelength range of 200-390 nm) are required. These sensors can
also determine carbon parameters (COD, BOD, TOC, SAC).
In-situ UV-VIS spectrometric sensors represent a precise measuring
technique with long-term stability, which permit quasi-continuous
recording of the selected parameter NO3 and NO2 in the smallest
measuring cycles of minutes.
The disturbance variables for optical measuring, such as
turbidity/suspended solids, are eliminated by spectral recording.
Thanks to integrated ultrasonic cleaning, a very long
maintenance-free operation is possible.
