Now available for rent, model 15i HCl analyzer. Using gas filter correlation technology, the Model 15i HCl measures the amount of Hydrogen Chloride in the sample. The Model 15i is based on the principle that Hydrogen Chloride (HCl) absorbs infrared radiation at a wavelength of 3.4 microns. Because infrared absorption is a nonlinear measurement technique, it is necessary for the instrument electronics to transform the basic analyzer signal into a linear output. The Model 15i HCl uses an exact calibration curve to accurately linearize the instrument output over any range up to a concentration of 5,000ppm. This state-of-the-art gas analyzer offers features such as an ethernet port, flash memory for increased data storage as well as being field upgradable. Ethernet connectivity provides efficient remote access, allowing the user to download measurement information directly from the instrument without having to be on-site. Easily programmable shortcut-keys allow you to jump directly to frequently accessed functions, menus or screens The larger interface screen can display measurement information and status while viewing menu and operational screens.
