Categories of Portable Gas Detectors and Their Application Features
The development of portable gas detector technology is advancing rapidly, with miniaturization and automation as its development direction, aiming to achieve long-term monitoring. Portable gas detector technology can be used for harmful gas detection, organic VOC gas detection, combustible gas detection, single gas detection, etc. Accurate judgment can be made through detection. Currently, it is widely used in the fields of industrial safety monitoring, indoor air quality detection, hazardous substance detection, environmental protection monitoring, etc. in the inspection and elimination of accident precursors. Let's take a closer look at the types and characteristics of portable gas detectors.
Portable gas detectors can be divided into diffusion type and pump suction type based on their sampling principle. The so-called diffusion type refers to placing the probe in a hazardous area for detecting gases, diffusing the gas to be measured from space into the probe, and placing the alarm in the monitoring room for indication and alarm. And pump suction is to pump the gas to be measured into the detection probe, and the suction pump is set together with the gas built-in detector, which is set at the dangerous location of the gas to be measured, so as to detect the execution indication and alarm function.
Portable gas detectors can be classified into toxic gas detectors and combustible gas detectors based on the type of gas they detect; According to the detection method, it can be divided into natural diffusion gas detectors and pump suction gas detectors; According to the number of detections, it can be divided into single gas detectors and multi in one gas detectors.
The toxic gas detector consists of a miniature plug-in electrochemical sensor located inside a 316 stainless steel housing, an intelligent transmitter module (ITM) encapsulated in epoxy resin, and a sensor splash guard. This plug-in intelligent sensor can automatically recognize ITM and achieve seamless connection on site. The operator operates through a magnetic rod. One of its main features is that its software can guide users to operate according to the program and LED displayed menu. Using gas detector technology to detect and analyze the concentration of toxic and harmful gases in the purified smoke and dust emissions, evaluate the purification effect, identify problems, and make timely improvements to ensure that the concentration of toxic and harmful gases emitted into the atmosphere meets national standards.
A combustible gas detector is a detector that responds to the concentration of a single or multiple combustible gases. The intelligent sensing transmitter used in the detector is the most comprehensive combustible gas sensing transmitter in terms of functionality. The infrared combustible gas detector is an ideal choice for the following application environments: frequent exposure to catalytic toxic gases, frequent emissions of highly flammable gases, oxygen deficient environments, and environments where detection is difficult to achieve
