info@inquiry@ato.com.cn Types of Portable Gas Detector
Portable gas detector technology can be used for harmful gas detection, organic voc gas detection, combustible gas detection, single gas detection. Through the detection can make an accurate judgment, at present in the accident precursor inspection, elimination, industrial safety monitoring, indoor air quality testing, dangerous substances testing, environmental protection monitoring and other fields to be widely used. Let's get to know what kind of portable gas detector is.
Portable gas detector can be divided into diffusion type and pump type according to its sampling principle. The so-called diffusive type is to put the probe in the dangerous area of detecting gas, and the gas to be measured in the space diffuses to the probe, while the alarm is placed in the monitoring room for indication and alarm. And pump suction type is to be determined gas pump inhalation detection probe, suction pump and gas built-in detector is set together, is to set the detector in the dangerous place of the gas to be measured, so as to detect the execution of instructions and alarm function.
Portable gas detector can be divided into toxic gas detector and combustible gas detector according to the type of detected gas. According to the detection method, can be divided into natural diffusion type gas detector and pump suction type gas detector; According to the detection quantity, it can be divided into single gas detector and multi-in-one gas detector.
The toxic gas detector consists of a miniature plug-in electrochemical sensor housed in a 316 stainless steel housing, an epoxy encapsulated intelligent transmitter module (ITM), and a sensor splash shield. This plug-in smart sensor automatically recognizes ITM and enables seamless field connectivity. The operator operates with a magnetic rod. One of its main features is its software, which guides users through programs and LED menus. The gas detector technology is used to detect and analyze the concentration of toxic and harmful gases in the smoke and dust discharged after purification, evaluate the purification effect, find problems and make timely improvement, so that the concentration of toxic and harmful gases discharged into the atmosphere can reach the national standard.
A combustible gas detector is a detector that responds to the concentration of one or more combustible gases. The intelligent sensor transmitter used in the detector is a fully functional combustible gas sensor transmitter. Among them, infrared combustible gas detector is an ideal choice in the following application environment: frequent exposure of catalytic gas frequently high combustible gas emissions, hypoxic environment, detection is not easy to achieve the environment
Diffused gas detector is used to test the sample gas flowing slowly into the instrument along with the free flow of air in the tested area. It needs to be placed on site. This method is affected by the detection environment, such as ambient temperature, wind speed, etc., and is not suitable for low-pressure air source. Diffused gas detector has the advantage of lower cost than pump type.
The pump-suction gas detector is equipped with a gas sampling pump. Its working mode is that the power supply drives the gas sampling pump to extract and sample the gas in the test area, and then send the sample gas to the instrument for testing. Pump type gas detector is characterized by fast detection speed, remote measurement of dangerous areas, maintenance personnel safety. Suitable for gas detector can not be placed in the field, and the reaction speed, differential pressure and other special requirements of the occasion.
Single gas detector, using high-performance catalytic combustion sensor, can be used for petrochemical industry, environmental accidents, natural gas, liquefied petroleum gas, gas and other industries to detect a variety of combustible gas, including: alkanes, liquefied petroleum gas, natural gas, hydrogen and so on. Its display unit is %LEL - low explosive lower limit, and the resolution is 0.1%LEL. In addition, the single gas detector has the characteristics of compact and novel appearance, easy to carry and so on. Its parameter setting and zeroing calibration process can be set to password protection to prevent the wrong setting and operation of non-qualified personnel. And the instrument is equipped with sound-light vibration alarm function. At the same time, according to the specific needs of users, the alarm can be set with muffler and latch function. The internal storage of the instrument can record the detection data for an additional 30 days (the recording interval is 1 minute). The user can upload the internal data to the PC or monitoring instrument through the infrared interface of the instrument itself for the convenience of query and analysis.
Multi-gas detector can be equipped with a single gas or multiple gas sensor instrumentation, can be configured with a single, two in one, three in one, four in one or any four kinds of toxic gas sensor or any single type of gas sensor for testing.
