Talking about the purchase of gas alarms

Gas alarm is a very important gas safety device. It is the last protection for the safe use of city gas. Its most critical performance is that it requires both a high sensitivity to the detected gas and a high stability and immunity to interference. Because the sensors used in alarms have different degrees of "drift" tendencies. Therefore, it is very difficult to make high-performance and high-quality gas alarms. When choosing to purchase a gas alarm, pay attention to the following points:

1, according to the use of gas purchased, gas alarm is generally not universal, natural gas occasions use natural gas alarm, artificial gas occasions should use artificial gas alarm, liquefied petroleum gas occasions should use liquefied petroleum gas alarm or use Generalized flammable gas detection alarms for liquefied petroleum gas calibration (Note: Gas fuel alarms that use local gas components for calibration and detection should be used for different gas components in different regions).

2, buy gas alarm should choose a good market reputation of the company's products, before the purchase is best to conduct some research, because on the one hand the market alarm products cohabitation, users do not know this product is very well; on the other alarm Is a long-term use of the product, no gas leakage can not see the performance and quality of the period, so its long-term stability requirements are very high, and the current gas alarm product standards in the assessment of its long-term stability is still insufficient, so The research and quality control of a product by a manufacturing company is very important for the product's performance and quality. You can also learn from the long-term use of the user's use of the product and product testing units issued by the use of gas alarms over the years the test results for reference.

3, the use of gas alarm should pay attention to the long-term stability and service life of the alarm, alarm, especially the sensor is a life span, the purchase should be informed to the vendors and production companies. At the same time, due to the importance of gas alarms used in public places for safety, the just-released Shanghai Gas Regulations stipulates that commercial gas alarms should be commissioned to regularly inspect professional inspection structures to ensure their normal use.
