ADVANCED POLLUTION INSTRUMENTATION Model T400 UV Absorption 03 Analyzer The Model T400 UV Absorption analyzer uses a system based on the Beer-Lambert law for measuring low ranges of ozone in A 254 nm UV light signal is passed through the sample cell where it is absorbed in proportion to the amount of ozone present. Periodically a switching valve alternates measurement between the sample stream and a sample that has been scrubbed of ozone. The result is a true, stable ozone All T Series instruments offer an advanced color display capacitive touch screen, intuitive user interface, flexible I/O, and built-in data acquisition capability. All instrument set up, control and access to stored data and diagnostic information is available through the front panel, or via RS232, Ethernet, or USB com ports either locally or by remote connection using the included APIcom™ software. user selectable ►► Single pass ultraviolet absorption Dual ranges and auto ranging ►► Large, vivid, and durable color graphics display with touch screen ►► Front panel USB connections for peripheral devices and firmware ►► 8 analog inputs (optional) ►► Adaptive signal filtering optimizes response time ►► Internal programmable zero, span and precision points (optional) ►► Comprehensive internal data logging with programmable averaging periods ►► Ability to log virtually any operating Free Customer Support by telephone and email for the life of the instrument
