Used VARIAN 959 #9394070 for sale

VARIAN 959 leak detector is a highly sensitive instrument designed for detecting the minute concentrations of gases that may be present in a vacuum environment. The system is capable of detecting leaks down to a level of 10-7 atm cc/sec, making it suitable for use in high purity and ultra high vacuum systems. 959 utilizes mass spectrometry technology to detect the presence of gases such as hydrogen, oxygen, and helium. This advanced method is extremely precise, allowing for fast and reliable leak detection. Mass spectrometry works by ionizing the sample gas and then analyzing the spectrum of ions created. This spectrum can be used to identify and quantify the gases present in an environment. The system is composed of three main components: a sample chamber, a Torr-seal port, and an ion-source valve. The sample chamber is a closed container which contains the sample gas. The Torr-seal port is connected to a vacuum or gas line and provides a path for the sample gas to be introduced into the sample chamber. The ion-source valve controls the ionization process, allowing for the introduction of either positive or negative ions into the sample chamber. VARIAN 959 also has a high-pressure safety signal which is used to alert the operator if the pressure increases beyond a specified amount. This feature helps ensure the safety of the user and the equipment. 959 is designed to provide quick and accurate detection of any leaks in a vacuum environment. The system is also easy to operate and maintain. By using a combination of precision and safety features, VARIAN 959 leak detector is a reliable and efficient tool for detecting gases in a vacuum environment.
