The ammonia gas detector works by using sensors to detect the concentration of ammonia gas in the air. If the concentration exceeds a pre-set level, the detector will activate an alarm, warning workers and alerting them to potential danger.
The ammonia gas detector is a device used to monitor the concentration which are widely used in various types of cold storage rooms, laboratories with ammonia, ammonia storage warehouses and other industrial places with ammonia, which can effectively prevent poisoning and other risks and ensure the safety of human life. The compact and economical design of the ammonia detector can be used in the case of a variety of harmful gases, the ammonia detector is highly waterproof, its IP66/67 housing can be completely submerged in water, and can resist EMI/RFI; Durable stainless steel alligator clip with built-in shock-proof jacket. Ultra-high acoustic alarms, flashing LED columns and built-in vibrators alert users to hazards. The easy-to-read, oversized display with built-in backlight ensures that data is read in low-light situations.
Precautions when using:
1.The calibration of the instrument according to the principle of the product, it is recommended that six months need to be calibrated by the standard ammonia concentration, the concentration of the standard gas can be configured according to the 50% proportion of the measuring range of the instrument, such as 100ppm measuring range of the instrument, the standard gas uses 50ppm standard concentration of gas. Configuration components for ammonia + Air proportional configuration, with a good, of course, if conditions can also be configured in accordance with the standard requirements of the measurement testing body to configure the concentration of three ranges to configure, respectively, 10%, 30% and 70% of the concentration of the measurement range, after configuration, respectively, through the three ranges of ammonia concentration calibration.
2.The use of the instrument precautions, first from the adaptive environmental conditions, the normal working requirements are that the test ambient temperature must be in the range of -20 degrees to +50 degrees, the humidity is 95%RH no condensation, the pressure is less than 100kpa, the dust concentration must not be too high otherwise it will affect the gas sensor contact gas. Blocking gas diffusion into the gas sensor affects the measurement. The previous several factors can lead to a reduction in the break life of the sensor. Therefore, the applicable industrial control conditions are very important, but it is necessary to pay attention to the application of non-conforming environment, time and conditions exceed the proportion to prevent irreversible damage.
3.The service life of the product, under normal circumstances, the life of different products is also different, the sensor needs to be replaced in time after the expiration, and then calibrated, usually the electrochemical ammonia sensor, the service life is two years. The principle of catalytic combustion is three years, and the corresponding sensor is purchased after the expiration.
