SF6 Gas Recovery and Filling Device


● Compact size, light weight, portable, with handheld snake probe and flexible connection wire.

● High sensitivity: Super sensing, responds to trace halogen gases, can detect gas leakage of more than 3g per year.

● Wide measurement range: The instrument can detect SF6 leakage within the leakage rate range of SF6 switchgear, with two switchable ranges.

● High accuracy: The instrument is calibrated using calibration methods, providing a highly accurate calibration curve, improving the credibility of SF6 leak detection results and the precision of quantitative leak detection.

● Intuitive display, audible and visual alarm: Uses digital LCD with backlight, providing simple and intuitive display. When SF6 is present, the instrument emits an audible and visual alarm.

● Fast response and short recovery time: Uses a new circuit structure, speeding up response and shortening recovery time, greatly facilitating on-site detection.

● Long operating time: Can operate for up to 5 hours, very suitable for field use, SF6 high-voltage switchgear factories, and research institutes.

● Rechargeable battery, can be used continuously for more than 5 hours at a time.
