 Description

The Model T100U Trace-level SO2 analyzer has been developed specifically to address the challenges of low level monitoring as required, for example, in the US NCore network.  It uses the proven UV fluorescence principle, and is designed to allow ultra-sensitive SO2 measurements while still meeting the requirements for use as a US EPA compliance analyzer.

The analyzer uses both the light and dark phases of the pulsed UV light source to continuously detect and correct for electronic noise, giving exceptionally stable and sensitive performance.  A separate UV detector allows the instrument to continuously correct for variations in lamp intensity.  Exceptional stability is achieved with the use of an optical shutter to compensate for PMT drift, and a reference detector to correct for changes in UV lamp intensity.  A hydrocarbon “kicker” and advanced optical design combine to prevent inaccuracies due to interferents.

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.

The Model T100U comes  with NumaView  Software. NumaView Remote PC Software allows for a remote connection with virtual interface and data downloading capability to analyzers operating NumaView Software.
