KWS-200 Online NH4-N Ammonia Nitrogen Sensor
Introduction
Kacise has taken a significant step forward in the field of
environmental monitoring by introducing an innovative online
ammonia nitrogen sensor. This remarkable sensor operates without
the need for any reagents, a feature that not only simplifies the
monitoring process but also aligns with the principles of being
green and non-polluting. It offers the advantage of real-time
online monitoring, allowing for immediate and continuous access to
crucial ammonia nitrogen data.
The sensor is ingeniously integrated with ammonium, potassium
(optional), pH, and reference electrodes. These electrodes work in
harmony to automatically compensate for potassium (optional), pH,
and temperature variations in the water. This advanced compensation
mechanism ensures the accuracy and reliability of the measurements,
providing valuable insights into the water quality parameters.
One of the standout features of this sensor is its straightforward
installation process. It can be directly put into operation,
eliminating the complex setup procedures associated with
traditional ammonia nitrogen analyzers. This direct installation
approach makes it a more economical, environmentally friendly, and
convenient option. By reducing the costs and efforts associated
with installation, it offers a practical and efficient solution for
various monitoring applications.
Furthermore, the sensor is equipped with a self-cleaning brush.
This ingenious addition prevents microbial adhesion, which is a
common challenge in many sensors. By minimizing the accumulation of
microorganisms, the maintenance intervals are significantly
extended, reducing the frequency of maintenance and associated
downtime. This leads to excellent reliability and consistent
performance over an extended period.
In terms of data output and integration, the sensor adopts the
RS485 output interface and supports the Modbus protocol. This
enables seamless integration with existing monitoring systems and
data acquisition platforms, facilitating easy data transfer and
analysis. The compatibility with widely used communication
protocols ensures smooth interoperability and simplifies the
integration process for users.
Overall, Kacise's online ammonia nitrogen sensor represents a
breakthrough in water quality monitoring, combining advanced
features, ease of use, and reliable performance to meet the
demanding needs of modern environmental monitoring applications.

Maintenance Methods and FAQ
Maintenance Schedule and Method
1. Maintenance Schedule
It is recommended to periodically calibrate or clean the sensor
surface according to the actual application scenario.
2. Maintenance Methods
Sensor maintenance
1) Sensor outer surface: Clean the outer surface of the sensor with
tap water. If there is still debris, wipe it with a soft, damp
cloth.
2) Check the cable of the sensor: the cable should not be tightened
during normal operation, otherwise the cable inside the cable will
be broken, causing the sensor to not work properly.
3) Sensor storage: When the sensor is not in use, the black plastic
cap should be fastened to check whether the sponge inside is wet.
If it is not wet enough, please add 3mol/L potassium chloride
solution and let the electrode be placed with potassium chloride.
Preserved in the solution.
The Matters Needing Attention
The probe contains sensitive optical and electronic components.
Make sure the probe is not subject to severe mechanical shock.
Damage to the sensor due to impact or man-made will not be covered
by the warranty. The sensor inlet water is not covered by the
replacement of the pH electrode.

Procedure to get NH3_N value
Figure 91:Flow chart to get NH3_N measurement
Start brush active – make the brush active once power on , then the
brush will work at the set interval time.
Get temperature and NH3_N values – Get measurement results
including temperature (C) and NH3_N (mg/L) after 20 seconds of
brush active.
(mg/L) after 20 seconds of brush active.
Note: Please pay attention to highlighted portion (red) in the flow
chart above. It’s highly recommended that customers get an average
NH3_N results after 10 consecutive measurements, then perform
display or other process.
