Teledyne T100 Manuale Utente

This section provides an overview of the Model T100 Analyzer, its features and its 
options, followed by a description of how this user manual is arranged. 

The Model T100 (also referred to as T100) UV Fluorescence SO

2

 Analyzer is a 

microprocessor controlled analyzer that determines the concentration of sulfur dioxide 
(SO

2

), in a sample gas drawn through the instrument’s sample chamber where it is 

exposed to ultraviolet light, which causes any SO

2

 present to fluoresce. The instrument 

measures the amount of fluorescence to determine the amount of SO

2

 present in the 

sample gas. 

The T100’s exceptional stability is achieved with the use of an optical shutter to 
compensate for sensor drift and a reference detector to correct for changes in UV lamp 
intensity. Additionally an advanced optical design combined with a special scrubber, 
called a "kicker" that removes hydrocarbons (which fluoresces similarly to SO

2

) 

prevents inaccuracies due to interferents.  

Calibration of the instrument is performed in software which stores SO

2

 concentration 

measurements made gas with when specific, known concentrations of SO

2

 are supplied 

to the analyzer. The microprocessor uses these calibration values along with other 
performance parameters such as the sensor offset, UV lamp intensity and the amount of 
stray light present and measurements of the temperature and pressure of the sample gas 
to compute the final SO

2

 concentration. 

Built-in data acquisition capability, using the analyzer's internal memory, allows the 
logging of multiple parameters including averaged or instantaneous concentration 
values, calibration data, and operating parameters such as pressure and flow rate.  Stored 
data are easily retrieved through the serial port or optional Ethernet port via our 
APICOM software or from the front panel, allowing operators to perform predictive 
diagnostics and enhanced data analysis by tracking parameter trends.  Multiple 
averaging periods of one minute to 365 days are available for over a period of one year. 

The features of your T100 UV Fluorescence Sulfur Dioxide Analyzer include: 

  LCD Graphical User Interface with capacitive touch screen 
  Ranges, 0-50 ppb to 0-20,000 ppb, user selectable 
  Dual ranges and auto ranging 
  Microprocessor control for versatility
