Model 300E Carbon Monoxide Analyzer
Instruction Manual
Some applications, such as EPA monitoring, require multipoint calibration checks
where Span gas of several different concentrations is needed. We recommend
using high-concentration, certified, calibration gas supplied to the analyzer through
a Gas Dilution Calibrator such as a T-API Model 700. This type of calibrator
precisely mixes Span Gas and Zero Air to produce any concentration level between
0 ppm and the concentration of the certified gas. This means that both the source
of Zero Air and Span Gas must be connected to the calibrator whose output is then
connected to the Pressure Span inlet on the Rear Panel of the instrument.
Figure 3-5 depicts the pneumatic set up in this sort of application of a Model 300E
CO Analyzer with Zero/Span Valve Option 50 installed.
Gas Pressure should be
