The nature of "SF6" gas
It is about 5 times the relative density of air. In order to facilitate transportation and storage, SF6 gas usually exists in a cylinder in liquid form.
The chemical nature of SF6 gas is very stable, it does not burn in the air, does not support combustion.. And does not react with water, strong alkali, ammonia, hydrochloric acid, sulfuric acid, etc.; when the temperature is lower than 150℃, SF6 gas is chemically inert and rarely melts in water .... Micro-melting in alcohol, no chemical effect on metals and other organic materials commonly used in electrical equipment. However, under the action of high-power arc, spark discharge and corona discharge, SF6 gas can decompose and liberate a variety of products...... mainly SF4 and SF2, as well as a small amount of S2, F2, S, F, etc.
Why should SF6 be tested?
The safety of SF6 has always received extensive attention. Although the normal SF6 gas is an inert gas that is colorless, odorless, has a density heavier than air... And is not easily mixed with air... It is not toxic to humans. However, under the action of high-voltage arc, SF6 gas will be partially decomposed... And its decomposition products are often highly toxic, even a small amount can cause death. So we need a portable toxic gas detector---sulfur hexafluoride SF6 sensor
portable toxic gas detector--Portable sulfur hexafluoride leak detector
Portable sulfur hexafluoride leak detector, a safety instrument developed and sold for the toxic gas of sulfur hexafluoride..... And a safety instrument for monitoring the concentration of sulfur hexafluoride gas. It has the characteristics of high detection accuracy and strong stability....., .....Relying on years of gas transmitter research and development experience, using mature, stable and long-life probe solutions.
SF6 gas sensor module adopts non dispersive infrared technology... Which has the characteristics of high sensitivity, high resolution, oxygen free dependence....... Stable signal, accurate measurement, low power consumption and long service life. SF6 gas sensor module has diffusion type and pump type, which can be selected according to the demand.
