SF6 Gas Leak Detector (Qualitative) is the culmination of30 years of leak detector manufacturing experience. As the most stable and most sensitive negative corona leak detector ever manufactured, we are proud to provide this tool. We have incorporated all our experience and years of customer feedback into this product, hoping to provide users with everything: price, performance, and reliability.
The core of this instrument is a microprocessor. It employs digital signal processing technology, making it possible to achieve better performance than previous analog circuits and sensor head signals. In addition, the number of components used in the circuit is reduced by approximately40%, thereby improving reliability and performance. The microprocessor monitors the sensor head and battery voltage in real time, up to4000 times per second, and can promptly compensate for even the slightest variation in signal pulsation. This makes the instrument a stable and reliable detection tool in almost all environments.
790B SF6 Gas Leak Detector (Qualitative) has added many user-friendly features in its design. The seven-level free setting of sensitivity allows the meter to increase sensitivity by64 times from level one to level seven; the unique three-color LED indicates progressive and wide-range leak sizes; indicates sensitivity levels; and provides actual voltage indication of battery level. Touch-type keyboard controls all functions; the novel housing design allows users to grip firmly for easy operation; visual indicator for intuitive reading during installation and use.
