SF6 Gas Quantitative Leak Detector
Executive Standard: DL/T596-1996
Application Occasions
The SF6 gas quantitative leak detector is very suitable for power supply departments, installation and maintenance units, and power test research institutes. It is also very suitable for SF6 high-voltage switchgear manufacturers as a supporting instrument for SF6 electrical equipment and export products, thereby enhancing the overall product grade.
Functional Features
● Compact size, light weight, portable, with a handheld snake-shaped probe and flexible connection cable.
● High sensitivity: Super sensing capability, responds to trace halogen gases, can detect gas leakage of more than 3 grams per year.
● Wide measurement range: The instrument can detect SF6 leakage within the leakage rate range of SF6 switchgear, with two selectable ranges.
● High accuracy: The instrument uses advanced calibration methods to provide high-accuracy calibration curves, improving the credibility of SF6 leak detection results and the precision of quantitative leak detection.
● Intuitive display with audible and visual alarm: Digital LCD with backlight for simple and intuitive display. When SF6 is present, the instrument emits an audible and visual alarm.
● Fast response and short recovery time: The new circuit structure speeds up response and shortens recovery time, greatly facilitating on-site detection.
● Long usage time: Can be used 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.
