HNL presents this SF6 Leak Detector as the most stable and sensitive wavelength NDIR sensor based SF6 leak detector. An advanced microcontroller is the heart of this unit. Its digital signal processing capability permits better management of the circuitry. SF6 has reduced components, enhance reliability and performance. The microcontroller analyzes the sample and voltage, compensates for even the most minor fluctuations in signal. This translates into a stable and dependable tool in almost any environment. Convenience features like large graphic display have been incorporated to enhance the usability of the GD – 104 (SF6). Display show a progressive and wide ranging leak size indication, communicates the sensitivity level, and provide a true indication.
