Introduction to Ammonia Nitrogen Sensor

Yushan Y560-A online ammonia nitrogen sensor, no reagent required, green and pollution-free, can monitor in real-time online. Standard configuration includes ammonium ion electrode, pH electrode, and reference electrode (optional for potassium ion), which automatically compensates for pH and temperature during the measurement of ammonia nitrogen in water, making the measurement values more accurate.
The Y560-A online ammonia nitrogen sensor can be directly installed, which is more economical, environmentally friendly, convenient and fast compared to traditional ammonia nitrogen analyzers. The sensor is equipped with a self-cleaning brush, which can prevent microbial adhesion, prolong maintenance cycles, and have excellent reliability. Adopting RS485 output and supporting Modbus for easy integration.

Sensor features:

1. Digital sensor, RS-485 output, supporting MODBUS;

2. No need for reagents, no pollution, more economical and environmentally friendly;

3. Automatically compensate for potassium ions (optional), pH, and temperature in water bodies;

4. Equipped with a self-cleaning brush to prevent microbial attachment and maintain for a longer period of time.

5. Note: Ionic electrodes are only suitable for freshwater applications and not for seawater.

Calibration steps for Y560-A ammonia nitrogen sensor

1. Required tools and raw materials
Required equipment:3 1L beakers, 1 pair of gloves

2. Calibration steps

There are two methods for user calibration of ammonia nitrogen sensors: 1-point calibration and 2-point calibration.

Perform 1-point calibration in 10ppm standard solution and change the K value of the sensor;

Two point calibration is completed in standard solutions of 10ppm and 100ppm, changing the sensor's k and B values.

(1) 1-point calibration steps (changing K value)

Step 1:Open the Yushan SmartPC testing software on the computer, click on "Connect" and "Measure", click on "Brush" in the "NH4-N" interface, and click on "Rotate Brush" in the "Wiper" interface to remove bubbles from the testing window. Then click "Start" to obtain real-time measurements of pH, NH4+, NH4-N, and temperature;

Step 2:Click "Stop" to end the data measurement, then click "Calibration". In the "Auto Calibration" interface, write the "Single Point/First Point Calibration Value" of 10, click "1 Point" and wait for the calibration value to stabilize. Click "OK" to complete the calibration. Click on 'Get' again and check if the K value is written correctly;

Step 3:Click "Start" on the "NH4-N" interface to obtain real-time measurements of pH, NH4+, NH4-N, and temperature. Check if NH4+is close to 10mg/L and verify if the calibration is successful.

(2) 2-point calibration steps (changing K and B values)

Step 1:Open SmartPC testing software on the computer, click on "Connect" and "Measure", click on "Brush" in the "NH4-N" interface, and click on "Rotate Brush" in the "Wiper" interface to remove bubbles from the testing window. Then click "Start" to obtain real-time measurements of pH, NH4+, NH4-N, and temperature;

Step 2:Click 'Stop' to end the data measurement, then click 'Calibration', and on the 'Manual Calibration' interface, click 'Get' to obtain the initial K and B values of the sensor. In the "Automatic Calibration" interface, write the "Single Point/First Point Calibration Value" of 10 and the "Second Point Calibration Value" of 100. Click "2 Points" to perform two-point calibration, wait for the calibration value of the electrode in the first standard solution to stabilize, and click "OK".

Clean the sensor with distilled water or deionized water, wipe it dry, and place it in the second standard solution（100mg/L）Wait for the calibration value of the electrode to stabilize in the second standard solution, and click "OK" to complete the 2-point calibration. Click on 'Get' again and check if the K and B values are written correctly.

Step 3:Click "Start" on the "NH4-N" interface to obtain real-time measurements of pH, NH4+, NH4-N, and temperature. Check if NH4+is close to 100mg/L and verify if the two-point calibration is successful.
