sf6 gas leak detector (qualitative) is the culmination of 30 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 signal processing than with previous analog circuits and sensor head signals. In addition, the number of components used in the circuit is reduced by about40%, thereby improving reliability and performance. The microprocessor monitors the sensor head and battery voltage in real time, up to4000 times per second, and can compensate for even the slightest variation in signal pulsation. This makes the instrument a stable and reliable detection tool in almost all environmental applications.
790B SF6 gas leak detector (qualitative) has been designed with many user-friendly features. The seven-level free setting of sensitivity allows the meter to increase sensitivity from level one to level seven by64 times; the unique three-color LED indicates progressive and wide-range leak sizes; indicates the sensitivity level; and provides actual voltage indication of battery power. Touch-type keyboard controls all functions; the novel housing design allows the user to grip firmly for easy operation; and the visual indicator is intuitive for installation and use.
