Used ROSEMOUNT 955 #112611 for sale

ROSEMOUNT 955 Residual Gas Analyzer is a device used to measure and analyze the composition of residual gas in vacuum systems. The device measures a range of gases such as O2, H2, CO2, CH4, N2, C2H6, CO, C2H4, and Ar. It is a self-contained system, containing both a residual gas analyzer and a controller. The device utilizes a heated inlet, along with a built-in evacuation and venting port, in order to reduce the sample volume and speed the measurements. The analyzer also has a large volume of sample processing capacity, making it highly accurate and reliable in the measurements it takes. The gas mass spectrometer is the heart of the system and is used to measure the presence of the individual gases in the residual gas sample. The mass spectrometer system works by heating the sample gas, causing ionization to occur, forming ions which are channeled through a magnetic field. The individual gasses in the sample are then separated from each other based on their mass-to-charge ratio and detected by a detector. The signal from this detector is then sent to the controller, providing the measured concentration of each species. 955 Residual Gas Analyzer is an excellent choice for those who need to measure the composition of residual gas in their vacuum systems. The device is highly accurate, and boasts a large sample volume capacity, allowing it to provide reliable gas composition analysis. The automated feature allows for continuous analysis, eliminating the need for repeat measurements or manual readouts. Furthermore, the self-contained nature of the device makes it repairable without relying on an external service, increasing flexibility, and cost savings in the long run.
