The method of using the ammonia gas detector is very simple. You only need to turn on the device. The program will guide the instrument to warm up automatically. After the warm-up is complete, it will automatically enter the measurement mode without any operation. All you need to do is take the instrument to the place where you need to test and watch the instrument display.
So it's that simple at the application level, it's completely automatic. This is the detection used. In addition, how to check the quality of the instrument is very simple. Ammonia is ubiquitous around us. I took the ammonia detector to the public toilets, and once I tried it, we all know that when you enter the public toilets, there is a strong dazzling breath. This is ammonia. The display of the instrument indicates that the instrument is normal. If your ammonia tester does not have any numbers, then pay attention to it, it may fail. In addition, there is a simple way to grab the urea used for fertilization in rural areas and put the ammonia gas detector on it. If there is no problem, if there is no data, you need to protect the sensor. These are the methods around us that make it easy to detect the quality of ammonia meters.
In addition, I will tell you some professional usage methods. The ammonia gas detector is a measuring instrument that can only be used after strict standard gas calibration. Otherwise, your test data may be degraded. The specific procedure should be to prepare a bottle of ammonia. Standard known concentration gas in the range of the gas detector. It is equipped with a professional pressure reducing valve flow control meter. The output flow is adjusted to 500ml / min. Use the meter calibration cover to enter the meter and observe for 2 minutes until the meter data is unchanged. Calibration accuracy. This is a professional calibration method.
In normal use, we need to pay attention to three points: this first point, do not use beyond the range, do not touch the concentration greater than the measurement range of the ammonia detector. Secondly, do not shake the instrument at will to prevent the electrolyte from being uneven inside the sensor and causing zero point drift. The third point is not to use it under high temperature, high humidity, and high pressure environment, to prevent the sensor from being affected by environmental conditions and causing liquid leakage and damage to the sensor.
