Ammonia nitrogen analyzer is one of the intelligent online chemical analysis instruments, is widely used in thermal power, chemical fertilizer, metallurgy, environmental protection, pharmaceutical, biochemical, food and tap water solutions such as continuous monitoring of ammonia nitrogen value and temperature. The monitoring data can be connected to the recorder through the transmission output to realize remote monitoring and recording, and can also be connected to the RS485 interface through the MODBUS-RTU protocol to facilitate the computer to realize monitoring and recording. At the same time, the device has two relay interfaces, you can set the alarm point output
* Minimum order quantity: 1 piece

How to use Ammonia nitrogen analyzer:
Electrodes are very delicate components and must be installed correctly. Incorrect installation can lead to electrode damage or irreversible damage. Electrodes are piped. Immersion. French installation can be.
Do not put the electrode directly into the water, should choose the electrode mounting bracket or flow cup fixation. Before installation, be sure to waterproof and close the raw material belt (3/4 thread) to avoid water entering the electrode and causing short circuit of the electrode cable.
During the water shutdown, ensure that the electrode is immersed in the measured liquid or wear a protective cap with protective liquid inside. If the temperature is low in winter and the water is stopped for a long time, add an antifreeze device or bring back the indoor water storage. Otherwise, the service life will be shortened.Ammonia nitrogen analyzer can also be used with the precision cloud platform to check monitoring data anytime and anywhere. Cloud platform can be customized, please contact customer service for details.
1. Set the system
Buzzer Setting: Sets the buzzer switch when the alarm is generated.
Backlight Settings: You can set the background brightness and on-screen duration.
Password Change: Allows you to enable or disable the password and change the password.
Factory Settings Specifies whether to restore factory Settings
2 Signal Setting
Electrode type: Set the type of electrode, ammonia nitrogen electrode and conductivity electrode.
Temperature compensation: Set automatic or manual temperature compensation, temperature range -20-80℃
3 Online calibration
Ammonia calibration: After entering the ammonia calibration screen, put the ammonia nitrogen electrode into 4.00 ammonia nitrogen standard solution and let it stand for a while. When the indicator number is stable, press the [Confirm] button; then put the ammonia nitrogen electrode into 6.86 ammonia nitrogen standard solution and let it stand for a while. When the indicator number is stable, press the [Confirm] button. Let it stand for a while, and press the “Confirm” button when the displayed number is stable. After the successful calibration is displayed, the calibration process of ammonia nitrogen is over.
Ammonia nitrogen correction: The measured ammonia nitrogen can be corrected.
4 Configure remote transmission
Remote Setting: includes two communication modes: 485 and analog. RS485: Sets the communication address and baud rate of the 485.
Emt: Set the corresponding value of 4mA and the corresponding value of 20mA for 4-20mA output.
