Used VARIAN 979 #9187162 for sale

VARIAN 979 is a leak detector designed to measure small amounts of leaking gaseous materials from industrial pressure systems. The device is based on an innovative non-contact acoustic method called passive sonic detection. This means that it can detect gas leaks even in difficult-to-access locations, without the need for probes or other intrusive instruments. The device is equipped with a microprocessor and includes two sound sensors that measure acoustic motion within the equipment. This allows it to identify both differential and absolute pressures, as well as various characteristics of sound waves. The device also has adjustable sensitivity settings, allowing the user to adjust the detection threshold according to the size and type of pressure system being monitored. The acoustic unit operates in the range of 100 Hz to 6 kHz and is powered through a 9-12V DC connection. The device can be either mounted directly to the machine or alternatively connected via a remote cable. The sensor is IP-rated for protection against the elements, and includes an infrared port for remote monitoring. Additionally, the unit has a built-in LED display which allows for multiple language selection and on-screen setup. 979 is designed to be a cost-effective leak detector for industrial pressure systems. It offers simple operation, requiring very little setup and maintenance. Additionally, its acoustic tool can detect most gases, including helium, nitrogen, oxygen, carbon dioxide, and hydrogen, allowing a broad range of applications. The device can even be used to detect minute amounts of hydrocarbon gases, making it suitable for natural gas and propane applications. Overall, VARIAN 979 is a sensitive and reliable leak detector that can detect even the smallest of gas leaks. Its non-contact acoustic asset provides excellent detection accuracy and its adjustable sensitivity settings allow for a wide range of applications. The device is also convenient to use and requires very little maintenance. It is the perfect choice for all industrial pressure systems.
