Understand your needs
When selecting a gas leak detector, first of all, what gas should be detected? In what environment? Portable or fixed? And other incidental functions. These usually have to be considered. Otherwise, the original plan to buy an oxygen detector will result in the purchase of an ozone detector, resulting in unnecessary economic losses.
Understand the operating conditions of the operating environment
All kinds of gas leakage detectors have strict requirements for the site environment, such as temperature, humidity, pressure, dust, flow, H2, silicon, etc. When selecting a gas sensor, we should try our best to understand the interference of other gases and environmental factors on the detection of the sensor, and avoid these factors to ensure its accurate detection of specific gases.
Understand site safety
In most cases, the site where the detector is installed and used has mandatory requirements such as explosion-proof. For example, the coal, petroleum and other chemical industries have very strict requirements on explosion-proof, and the instrument itself needs to be explosion-proof with explosion-proof certification. Other working conditions may require the gas leakage detector to have certificates such as environmental protection certification or measuring instrument license.
Understand the functional requirements for use
The general function of the gas leakage detector is to detect the gas concentration and alarm when it exceeds the standard. The user can set the alarm value according to the use situation, including the vibration, sound and light and other reminder functions, which are applicable to various complex detection environments and ensure the safety of operators. However, many users not only need these functions, but also signal output. There may be other special requirements, such as network interface and wireless signal, which need to be considered by users.
