1.What is ammonia?
Ammonia (NH3) is a colorless and strongly pungent odor gas, lighter than air (specific gravity of 0.5), can feel the lowest concentration of 5.3ppm, ammonia is mainly used as a refrigerant and to make ammonium salt and nitrogen fertilizer, because the price is cheap, the refrigerator is also cheap and fluorine-free. Therefore, basically, industrial refrigeration requirements are not particularly high in the case of ammonia will be considered as a refrigerant. Ammonia leakage is toxic, polluting the environment, flammable and explosive, etc. The explosion limit of ammonia in the air is 16 ~ 25%, and the concentration of more than 15% has the risk of igniting. Use an ammonia gas detector to check whether the concentration of ammonia in the field environment exceeds the standard.
2.What are the dangers of ammonia?
The harm of ammonia leakage itself is toxic, which will cause damage to respiratory tract and eyes. Ammonia is an alkaline substance, which corrodes and stimulates the skin tissues in contact. If in the leakage area, the liquid ammonia sprayed into the body will affect the skin, absorb the water in the skin tissues, denaturate the histone, saponify the tissue fat, and destroy the cell membrane structure. Ammonia has a very high solubility, so it mainly irritates and corrodes the upper respiratory tract of animals or humans, weakening the body's resistance to disease. Prolonged exposure to ammonia can cause reflex respiratory arrest. If liquid ammonia leakage occurs, the valve should be quickly closed, the power should be cut off, and the upward vent should be evacuated. If conditions are available and fast enough, a gas mask can be worn.
3.The role of ammonia detector:
Ammonia gas detector is used to detect the concentration of ammonia in the environment of the electronic instrument, the use of imported electrochemical sensors, with signal stability, high precision, explosion-proof structure design, LCD/LED screen real-time display of ammonia gas concentration and other advantages, can be customized according to the actual needs of the range and output signal, to ensure uninterrupted operation in harsh working environment conditions, can be carried.
Ammonia gas alarm is an instrument that detects the measured gas in real time, indicates the ammonia concentration, and can issue an alarm when the set concentration is reached. It consists of three parts: sampling, detection, indication and alarm. The product is used to detect dangerous places where ammonia gas leaks.
4.Description of the main parameters of ammonia detector:
(1) Detection range: the concentration level of the measured gas that the monitor can accurately measure under normal working conditions;
(2) Indicating value error: under test conditions, the difference between the indicating value of the detector and the concentration value of the standard gas used;
(3) Alarm error: under test conditions, the difference between the alarm indicating value and the alarm setting value of the detector;
(4)Response time: under test conditions, under test conditions, from the detector contact with the measured gas to reach a stable indication of the time.
Ammonia gas monitor is applied to various types of cold storage rooms, laboratories with ammonia, storage warehouses and other industrial places with ammonia, which can effectively prevent poisoning and explosion accidents and ensure the safety of life and property. It is widely used in metallurgy, power plants, chemical industries, mines, tunnels, tunnels, underground pipelines and other places to effectively prevent ammonia leakage accidents.
