Abstract

The invention discloses a portable gas measuring device, which is characterized in that it includes a sealing and anti-leakage device, an electric air pumping device and a setting measurement control system. The gas sensor, the annular sealing combination cone is composed of the cone head, the cone body and the annular positioning sleeve. The fixed positioning ferrule is made of corrosion-resistant stainless steel. In general, the electric air extraction device includes a glass container, a motor, a reciprocating rod, a sealed air-tight plug and a protective contact, and the setting measurement control system includes a control operation box, a touch screen, buttons, sensors and an alarm. The invention can measure different types of gas samples, has good leak-proof sealing performance, is convenient to use, and has fast sampling speed, and is suitable for taking gas samples in the field of environmental protection or scientific research laboratories.

Description

technical field [0001] The invention relates to the field of gas measuring devices, in particular to a portable gas measuring device. Background technique [0002] With the continuous development of society, my country's environmental pollution has deteriorated sharply. Among them, air pollution has become particularly prominent in recent years. At present, the frequency of occurrence of smog is increasing every year in large and medium-sized cities with relatively fast economic development in my country. Smog is caused by air pollution, in order to solve the problem of smog. Atmospheric pollution must be started first, and research experiments measure the components of relevant pollutants or polluting gases in the atmosphere. Therefore, it is necessary to accurately collect or obtain gas samples for subsequent in-depth research on gas samples. However, the traditional gas sampling method has the following problems: 1. Sampling of special corrosive gases; 2. Quantitative...
