How far can the range of your gas detectors be measured?
Answer: This question is often asked by users, who mistakenly think that the gas detector can detect a long distance. In fact, there is a misunderstanding here. Gas detectors, especially fixed gas detectors, are generally diffuse, that is Said the gas needs to diffuse to the sensor heads for gas detection before they can detect the concentration. Otherwise, even if the toxic gas is nearby, it will not be detected. To give a simple example: the human sense of smell is a very sensitive organ. It can ask about the trace gas in the air to the level above ppb, so we sometimes need to get very close to ask, and sometimes we can smell it from a distance. To, this is due to the air flow direction and concentration ratio. The gas is dissolved in the atmospheric air. Due to the flow of the wind, it may not be detected by the gas detection equipment next to it. As the gas flows farther away from the gas leak point, the gas concentration will be lower, so the gas concentration is detected in the distance. Safe, does not mean that all locations are safe, the concentration is so low. There is no strict standard for how far to install one. Only the distribution of the location of the hazard source should be reasonably arranged according to the site conditions. It is recommended to install one device within a range of 20m2, or install one device within a range of 10-20 meters.
What are the environmental conditions for installing the gas detector?
Answer: Gas detectors all have their own working conditions. We mainly need to pay attention to the basic conditions of humidity, temperature, and pressure. Generally, the installation in our environmental workshop is more suitable. Basically, it can be directly installed and fixed, but we When installing in confined spaces, such as pipes, flues, and these special environments, we must pay attention to understanding the working conditions. Most of our gas detectors, no matter what brand, can adapt to the conditions. Normal temperature; -20 to 50 degrees, humidity below 90% without condensation, pressure in the range of 100kp. Once the environmental conditions are not in it, it will affect the accuracy of the measurement and the service life of the instrument. At this time, we must consider adding gas pretreatment equipment. To carry out gas processing to allow the gas that meets the conditions to enter the gas sensor head.
Does it have any effect if the installation location is too dusty?
Answer: The dust in the gas is too large, which will easily cause the gas sensor of the gas sensor to be adsorbed and cause blockage, and the detection accuracy will decrease. Therefore, once it is used in a high dust environment, the dust must be filtered, and the dust should be cleaned regularly depending on the dust situation. Be careful not to wash it with water or wipe it with a solution such as alcohol. Only clean the sensor surface with a clean soft cloth.
