With the enhancement of environmental protection awareness and the increasingly serious water pollution, ammonia nitrogen monitor is widely used in major industries and fields as an important water quality monitoring equipment. However, there are often some problems that arise during the use of ammonia nitrogen monitors. This article will introduce the common problems and solutions of ammonia nitrogen monitor to help users better use the device.
Problem 1: The monitoring instrument is faulty or cannot be started normally.
When using an ammonia monitor, there may be times when the instrument malfunctions or does not start properly. First of all, the user can check whether the power supply of the instrument is well connected and whether the power switch is turned on. If there is no problem with the power supply, check whether the relevant cables are loose or broken. If there is no problem with the above, it may be that the internal components of the instrument are faulty, and you should contact a professional maintenance personnel for treatment or repair.
Problem 2: Monitoring results are inaccurate or unstable.
*The monitoring results of the ammonia nitrogen monitor are closely related to the actual situation, so if the monitoring results are inaccurate or unstable, it is necessary to find out the problem. First, check that the monitoring instrument is properly calibrated and that the calibration is performed periodically. If the calibration is incorrect, it can be recalibrated to ensure accuracy. Secondly, the interference of environmental factors on the monitoring results should be excluded, such as whether the changes in temperature and humidity are within a reasonable range. Finally, check whether the sensor is clean, whether there are impurities or dirt adherence, and if so, clean or replace it in time.
Problem 3: The monitoring instrument will be abnormal if the working time is too long.
*When the ammonia nitrogen monitor is running continuously for a long time, there may sometimes be abnormal conditions, such as the display screen is dimmed, the instrument is heated, etc. This may be due to the high temperature inside the instrument, resulting in poor heat dissipation. The solution is to clean the heat dissipation holes of the instrument in time to ensure good heat dissipation. At the same time, the working time of the instrument should be properly controlled and continuous use should be avoided for too long to reduce the burden on the instrument.
Problem 4: The adaptability of the monitoring instrument to a specific sample.
*Ammonia nitrogen monitors are generally able to adapt to a variety of samples, but adaptability issues may arise when faced with some special samples. For example, samples with high salt concentrations may cause corrosion of the sensor electrodes, which can affect the accuracy of the monitoring. The solution is to select a sensor that is suitable for high salt concentrations, or dilute it before use. Similar measures can be taken for other special samples to ensure the accuracy of the monitoring results.
