Nowadays, everyone has a more and more thorough understanding of ammonia is a toxic gas, including casualties caused by ammonia leakage in recent years, and all walks of life are becoming more and more aware of the safety of ammonia places. Ammonia detectors are also increasingly used in all walks of life. For example, places where ammonia is used, such as cold storage, food enterprises, compressor rooms, chemical plants, chemical fertilizer plants and power plants, are worried that ammonia leakage will affect the safety of operators. ammonia detector has become a detection and alarm device for operation safety. However, in the daily use of ammonia gas detector, in order to prolong the service life of the equipment, the following matters should be paid attention to:

1. The calibration of the instrument is based on the principle of the product, it is suggested that the instrument needs to be calibrated once every 6 months through the standard ammonia concentration. The concentration of the standard gas can be configured according to 50% of the measurement range of the instrument. For example, for an instrument with a measurement range of 100ppm, the standard gas uses a gas with a standard concentration of 50ppm, and the configuration composition is ammonia + air. It is good to match 1 kinds, of course, if conditions permit, the concentrations of the three measuring ranges can also be configured according to the standard requirements of the measuring and testing organization, which are 10%,30% and 70% of the measuring ranges respectively. After configuration, the ammonia concentrations of the 3 measuring ranges are respectively introduced for calibration.

2. the precautions for the use of the instrument are, first of all, from the environmental conditions to which it is adapted. the normal working requirement is that the test environment temperature must be in the range of -20 degrees to +50 degrees, when the humidity is 95% RH and the pressure is less than 100kpa, the dust concentration shall not be too high, otherwise it will affect the gas sensor to contact the gas and prevent the gas from diffusing into the gas sensor to affect the measurement. Several of the foregoing factors may result in a decrease in the broken life of the sensor. Therefore, the applicable industrial control conditions are very important, 1 when applied to non-conforming environments, attention must be paid to the fact that the proportion of time and conditions exceeds the cost of preventing irreversible damage.

3. The service life of the product. Under normal circumstances, the service life of different products is also different. The sensor needs to be replaced in time after expiration, and then calibrated. Usually, the electrochemical ammonia gas sensor has a service life of two years.The principle of catalytic combustion is 3 years, and the corresponding sensors are purchased only after the expiration. It is not recommended to stock the sensors in advance, because the sensors have an inventory life, and they will fail even if they are bought back in advance.

4. regarding the vibration and charging of portable instruments during use, these basic knowledge will not be explained in detail here, because this product is the same as most products, and the basic requirements are the same.

the above-mentioned matters needing attention in the use of ammonia gas detector are shared here. in general, ammonia gas detector is configured in the ammonia gas use place to monitor the ammonia content on site in real time, which can ensure the personal safety of operators.
