Used VARIAN 979 #293792512 for sale

VARIAN 979 is a computer-based leak detector used to measure extremely low-level leaks in closed systems. Typical applications include refrigeration, gas analysis, industrial process control, medical equipment and automotive testing. 979 utilizes a condensation nucleus counter (CNC) profiler to measure the amount of gas leakage. The profiler is capable of counting particles per million (ppm) in the sub-ppb range and is extremely sensitive, allowing it to detect extremely tiny leaks. VARIAN 979 consists of a pressure-tight main frame and control circuitry that is housed in an easy to use unit. The main frame consists of an adjustable pressure chamber, two mass spectrometers and two molecular pumps. The molecular pumps draw in the sample gas and then feed it to the mass spectrometers, which measure the amount of gas molecules in the sample. The control circuitry consists of a computer, isolated voltage control and power supply, LCD display, temperature control, and data logging capabilities. 979 includes numerous features such as a tutorial, a calibration routine, data output, and an integrated leak test system. VARIAN 979 is also equipped with an ultrasonic double valve system to ensure precise measurements by compensating for any variation in pressure due to temperature or altitude. Additionally, 979's advanced features such as real-time data logging, pressure calibration, and calibration routine for each tested gas make it ideal for research and educational uses. VARIAN 979 achieves unprecedented accuracy and sensitivity in leak detection by utilizing a combination of its high-precision CNC profiling and advanced electronics. This allows 979 to measure leak rates down to a part-per-quadrillion range of sensitivity. With its ability to detect very low leak rates, the user can easily quantify the amount of leakage with greater accuracy. In addition, VARIAN 979 is equipped with a wide range of measuring capabilities such as pressure and temperature analysis and real-time data logging that make it ideal for industrial leak detection applications. 979 is an intuitive and user-friendly system that is capable of leak detection at a part-per-quadrillion level. Its high-precision CNC profiler, advanced electronics, and wide range of measurement capabilities make it an ideal choice for industrial and research applications. With its ease of use and unparalleled accuracy, VARIAN 979 can provide reliable and high-resolution leak measurements for any industry.
