1. This probe is designed for use where it is necessary to put the probe tip in areas not accessible with the 32 inch telescoping probe with dust filter and applications where the probe tube must be collapsible for storage See General Parts List on page 84 for probe ordering information 20 Optional Accessories EAGLE 2 Operator s Manual External Dilution Fittings Two external dilution fittings are available for the EAGLE 2 a 1 1 dilution fitting and a 3 1 dilution fitting They are designed to mate with the inlet fitting and accept a sample hose or probe The fittings are made with brass and nickel plated brass and are appropriate for use with the four standard gases The 1 1 fitting is normally used when it is necessary to introduce air into a sample that has no oxygen or a very low level of oxygen such as a nitrogen purged sample Both the 1 1 and 3 1 fittings can also be used when one of the target gas levels in the sample area will likely be present in a concentration above the detection range for that gas Since the fittings partially consist of unplated brass they are not appropriate for detection of elevated levels of H S or of gases that are easily absorbed such as Cl or SO TIL 1 1 Dilution Fitting 3 1 Dilution Fitting Figure 14 1 1 and 3 1 Dilution Fittings EAGL
