Gas detectors can be divided into two types: fixed and portable according to occasions and mobility.
In terms of use, the portable gas detector is used in inspections to detect the gas concentration of possible escape points in the factory or emergency response. It is characterized by lightness and can obtain measurement data in a short time;
The fixed gas detector is mostly used for long-term monitoring in factories, such as explosion-proof areas, which are characterized by long-term monitoring and can save human resources.
The following factors should be considered when choosing a gas detector:
- Understand your needs
When choosing a gas detector, we must first determine what gas to detect? In what environment is it used? Portable or stationary? And other ancillary functions.
- Understand the working conditions of the use environment
All kinds of gas detectors have strict requirements on the on-site environment, such as temperature, humidity, pressure, dust, flow, H2, silicon and so on. When choosing a gas sensor, you should know as much as possible about other gases and environmental factors that interfere with the sensor's detection, and avoid these factors to ensure that it can accurately detect specific gases.
- Understand the safety situation on site
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 for explosion protection, requiring the instrument itself to be explosion-proof and with explosion-proof certification. Other working conditions may also require gas detectors to have certificates such as environmental protection certification or measurement instrument permits.
- Understand the functional requirements use
The general function of the gas detector is to detect the gas concentration, alarm when exceeding the standard, etc.
The user of the Baosian gas detector can set the alarm value according to the use situation, and it also includes the reminder functions such as vibration, sound and light. It is suitable for various complex detection environments and protects the safety of operators.
But many users not only need these functions, signal output is one aspect, and there may be some other special requirements, such as network interfaces and wireless signals, etc., which need to be considered by users.
