SF6 gas quantitative leak detector has high sensitivity, wide measuring range, advanced calibration method and high accuracy calibration line, which improves the reliability of SF6 leak detection results and the accuracy of quantitative leak detection. It is a necessary testing instrument for power supply departments, installation and maintenance units and electric power test research institutes. Based on years of experience, we have summarized some problems encountered in the use of SF6 gas qua

Because the SF6 gas density relay like other manometers after a period of use, its alarm and lock value will produce a certain drift; In addition, because the contact action of the density relay is not frequent, the contact action may be insensitive or ineffective. If not inspected, there is a security risk.

High frequency oscillation electrodeless ionization type SF6 leak detector It is the use of high frequency oscillation electrodeless ionization principle. The resonant circuit composed of the high-frequency electric field electrode C on both sides of the ionization chamber and the high-frequency oscillation coil L has a high quality factor Q, because the gas in the ionization chamber is very thin and it is easy to ionize. When there is no SF6 gas in the ionization chamber, the Q value decreases

SF6 quantitative leak detector is mainly used in high pressure SF6 equipment gas leakage measurement and leak point search. SF6 gas quantitative leak detector is suitable for the power supply department, installation and maintenance units and electric power test research institute, but also very suitable for SF6 high-voltage switch factory as SF6 electrical equipment and export products supporting instruments, thereby improving the overall product grade.
