Note: The above prices from the network, for reference only.
Two, how to choose the right gas leakage alarm
In the purchase of gas alarms, pay attention to the comprehensive consideration of a variety of factors, including the use of the actual performance of the product, the brand and after-sales service and so on, measure and then choose a quality product, then how to choose a gas alarm? Selection of gas alarms to consider the main factors are:
1, the type of gas
To buy according to the type of gas used, some gas alarms are not universal, natural gas occasions to use natural gas alarms, artificial gas occasions should be used in the case of artificial gas alarms, liquefied petroleum gas occasions should be used in the case of liquefied petroleum gas alarms or liquefied petroleum gas calibrated with the common combustible gas Detection of alarms (Note: the composition of gas in different regions is different, should be used to calibrate and detect gas alarms with local gas composition).
2, stability
Purchase of gas alarms should choose the market reputation of the enterprise's products, the best research before buying, because on the one hand, the market alarm products are mixed, the user will not be very well known to the product; on the other hand, the alarm is a long-term use of the product, no gas leakage can not be seen in the period when the performance and quality, so the long-term stability of their The requirements are very high.
3, response time
The response time of the gas alarm refers to the time interval from the alarm is triggered to the system to display the detection of gas, which is a measure of the basic indicators of the function of the gas alarm system, a good gas alarm must have the ability to detect and detect the results of the timely manner with the appropriate way to display. Alarm response refers to the time interval from the alarm site alarm to the control center to display the alarm status. It includes the alarm delay, communication establishment time and control system equipment (generally sound, light display) delay, etc..
4, detection sensitivity
Security system designed for a certain range, when the gas reaches the alarm concentration in this range, the detector in time to detect, send an alarm signal. Detectors in the installation site of gas leakage sensing ability, usually to the lower limit of the explosion of different gases of different alarm concentrations of 25% or less.
5, service life
The use of gas alarms should be concerned about the long-term stability of the alarm and service life, alarms, especially its sensors have a life expectancy, should be purchased from the seller and manufacturer to understand.
6, after-sales service
Gas alarm products after the sale is also a very important part of the process, be sure to find a good after-sales service manufacturers, encountered problems can be resolved in a timely manner.
