Many people buy gas detectors only pay attention to what kind of gas can be detected, but when they see the manual, they find that they have bought the wrong one. Forcibly using them will only cause various failures one after another. In fact, as long as you clarify the following five steps and consult customer service in detail, you will not make mistakes.

Firstly,identify your needs

When choosing a gas detector, what gas must be clearly detected? In what environment is it used? Portable or stationary? And other accompanying features. These reasons usually have to be considered. Otherwise, there will be an ozone detector that was originally intended to buy an oxygen detector, which will cause a big oolong, which will not only delay things, but also cause unnecessary economic losses.

Secondly, clear the operating conditions of the environment

Various types of gas detectors have strict requirements for the on-site environment. Generally speaking, the temperature is -20 ~ 60 ℃, the humidity is 0-95% RH, the pressure is 80-120Kpa, and so on, including dust and flow. Because other impurities in the environment can have a huge impact on test results, causing unforeseen losses. At the same time, understand the working conditions on the site and provide this information to the manufacturer in time, and the manufacturer will have a corresponding solution.

Thirdly,Clarify site safety

In many cases, the site where the gas detector is installed has mandatory requirements such as explosion protection. The coal, petroleum and chemical industries have very strict requirements for explosion protection, and the instruments themselves need to be explosion-proof with explosion-proof certification. Other environments may require certificates such as environmental certifications or permits for measuring instruments.

Fourth. Define the functional requirements for use

The general function of the gas detector is to detect the gas concentration and alarm for exceeding the standard. But many customers need not only these features, but also additional features. Signal output is one aspect, such as current output, digital signal output, voltage output and digital output. There may be other special requirements such as network interfaces and wireless signals. At the same time, data recording and processing are more common requirements.

Fifth, clear sensor origin

The sensors of many gas detector manufacturers are nominally foreign sensors. In fact, this is not always the case. There are often domestic sensors that use imported sensors to impersonate imported sensors to pit consumers. When encountering such a situation, it is necessary to carefully check the product information, and if necessary, to sign a sales contract to protect their rights. At the same time, we recommend that you try to purchase authentic Porsche electronic products through official channels in order to obtain a satisfactory product experience and service.
