Used ROSEMOUNT DC-190/183 #9004999 for sale

ROSEMOUNT DC-190/183 Residual Gas Analyzer (RGA) is an ionization-based instrument used to measure gas concentration in vacuum systems. It provides fast, continuous analysis of residual gases that can help to identify and prevent contamination, ensure process control, and support leak detection. ROSEMOUNT DC-190/183 RGA includes a mass filter that separates the gas species entering the instrument, allowing for accurate and wide-ranging measurements. The instrument is powered by an advanced microprocessor and includes a user-friendly operating system and menu structure. Sampling and analysis is performed with the instrument connected directly to a vacuum system. The mass filter is heated so that the particles passing through the filter are ionized, producing an electrical current, which is then detected and measured. ROSEMOUNT DC-190/183 RGA utilizes an ion source to produce secondary ions. This process is referred to as secondary electron impact ionization. The mass filter consists of an array of lenses and magnets that allow for finer mass resolution. This mass filter produces broad species-specific spectra, providing the operator with accurate information related to the gas species present in the system. This instrument is capable of providing a wide range of measurements, including mass and relative number concentration, that are related to contamination levels in gas systems. The instrument can identify gas species in the parts per billion (ppb) range and below. It also can measure and report the quantity of over 500 gas species. ROSEMOUNT DC-190/183 RGA is installed in numerous process industries, such as semiconductor and R&D, aerospace, automotive, medical, and power. The instrument is designed and certified to meet industry standards. It comes with comprehensive user documentation and is backed by field service and support staff for maintenance and technical assistance.
