How to choose the right gas alarm?

2020-03-30

With more and more emergencies in society, gas alarms have belonged to the indispensable life, that selection of gas alarms we have what method can be quoted, the following by Shenzhen Puliton Electronic Technology Co:

We should know the national standards for the variety of gas alarms. Gas alarm can be divided into combustible gas leak detector, combustible gas alarm controller, combustible gas detector, household combustible gas alarm four series of products.

Leak detector is small in size, can be carried or handheld, the primary application for gas handling leakage and patrol. If there is a gas leak, the leak detector will announce sound and light alarms, together with the digital display of the gas concentration, so as to adopt timely safety measures to avoid explosions and other malicious accidents.

Selection method:

1, clear detection of the use of selected instrument varieties, portable detectors and fixed detectors

2, select the gas alarm category
In short, the detection of harmful gases have two purposes, the first is to measure the explosion, the second is to measure the poison. The so-called explosion detection is to detect the risk of gas content, overspending alarm, in order to prevent the onset of explosive incidents; toxicity detection is to detect the risk of toxic gas content, overspending alarm, in order to prevent staff poisoning. Measurement of the scale of the explosion is 0 ~ 100% LEL, measurement of the scale of the toxicity of 0 ~ tens (or hundreds) ppm, the difference between the two is very large.

Risky places harmful gases have three conditions, first, non-toxic (or low toxicity) combustible, second, non-combustible toxic, third, combustible toxic. The first two conditions are easy to determine, the first test explosion, the second test toxicity, the third condition if there are personnel exposed to test toxicity, such as no personnel exposed to test explosion.

Explosive selection of combustible gas alarms, toxic selection of toxic gas alarms.

Production or storage positions for long periods of time running leak detection selection of fixed alarms; others, such as maintenance testing, emergency testing, access to testing and inspection tours, such as the use of portable instruments.

3, clear detection goals, select the best type of instrumentation
Instrument type contains manufacturers, functional objectives and detection principle of the three main elements, the detection principle of the gas alarm to be accustomed to the detection of the target and the requirements of the detection environment.
