HNL is proud to present this detection tool as the most stable and sensitive negative corona SF6 leak detector ever made. An advanced microprocessor is the heart of this unit. Its digital signal processing capability permits better management of the circuitry and sensing tip signal than ever before. Additionally, the number of components used in the SF6 circuit is reduced nearly by 40%, thus increasing reliability and performance when searching for leaks. The microprocessor monitors the sensing tip and battery voltage levels 2000 times per second, compensating for even the most minor fluctuations in signal. This translates into a stable and dependable tool in Convenience features have been added to enhance the usability of the detector. It provides seven levels of sensitivity from level 1 to level 7. Its unique tri-color LEDs show a progressive and wide ranging leak size indication, communicate the sensitivity level, and provide a true voltage indication of battery power level. A tactile keypad controls all functions of operation. A revolutionary new case design gives the user grip and control, and places the visual indicators
