All SpectraSensors TDL gas analyzers employ the same design and hardware
platform. Measuring different trace gases in various mixed hydrocarbon
background streams is accomplished by selecting a different optimum diode
laser wavelength between 700 to 3000 nm, which provides the least amount
of sensitivity to background stream variations.
Getting Familiar with the SS2100i-1
The SS2100i-1 consists of a single enclosure containing two electrical assembly
panels. Figure 1–5 shows the front, rear and bottom of the analyzer.
