High purity sulfur hexafluoride is stable,safe and non-toxic at room temperature.But if the gas is not pure,it is not only harmful to the human body,but also corrosive to the electrical equipment,resulting in leakage.Therefore,it is very important to ensure the purity of the gas.

　　To detect gas purity,sulfur hexafluoride gas purity analyzer is generally used.There are different types and prices of high-purity sulfur hexafluoride purity analysis instruments on the market.Thermal conductivity method is the main method to detect gas purity.

　　However,the thermal conductivity method also has some defects,that is,there is a problem of temperature drift,so the test results of high-purity sulfur hexafluoride vary greatly,and the test results are different at different temperatures.

　　The new analyzer used by sulfur hexafluoride manufacturers uses SF6 gas mixed with air and nitrogen to detect the method,which can accurately detect the purity of the gas.For more information,call 139-4929-0069.
