VARIAN 979 is a reliable, high quality leak detector with an advanced design that is constructed for industrial applications. It can detect leaks with a wide range of sensitivity levels, from extremely low levels of 0.01 mbar*l/s to higher leakage rates of up to 20 mbar*l/s. It is equipped with a sensing interface that provides fast and repeatable measurement of controlling variation in pressure and flow regulation. 979 utilizes the sniffing principle for its detection of leaks. It features an ultrasonic probe, a long flexible hose, and a large snorkel. The ultrasonic probe is used to detect the sound created from escaping gases. The soundwave then travels up the flexible hose and is collected in the snorkel. From there, it passes through to the control unit, which signals a warning that the unit has detected a leak. VARIAN 979 is also equipped with a digital control panel, which allows the user to set and adjust the sensitivity and leakage detection levels to suit the application. Additionally, it provides stored setups to allow for quick and easy setup changes, and a signal operation indicator to monitor pressure and flow. 979 utilizes a smart filter system to ensure that the leak detector is able to distinguish between gases such as oxygen, nitrogen, water vapor, and hydrocarbons. This helps to eliminate false detection signals. VARIAN 979 also features an automatic shutoff and purge system, which helps to reduce the time required to establish the initial setup. 979 is designed for use in industrial environments, such as manufacturing plants, refineries, and power plants. In addition to its high quality leak detection capabilities, VARIAN 979 also has additional features such as a built-in keyboard and display, which allows for data logging and graphing. 979 is a reliable, cost-effective leak detector that is designed to perform consistently in industrial applications. Its advanced electronic sensing and control systems ensure that the device can detect leaks with up to 20 mbar*l/s of sensitivity, and its filter system ensures that false signals are eliminated. With a digital control panel and preset setups, VARIAN 979 is designed to make running tests and detecting leaks as effortless and efficient as possible.
