4.9. Pure Blends with Incorrect Component Ratios
The Pur•Chek™ Pro has the ability to detect blend ratios that have been altered by contamination. As
stated above, the blends that can be
identified
and
analyzed
are as follows.
•
R134A
•
R22
•
HC (hydrocarbons)
•
R404A
•
R407C
•
R410A
If one of the multi-component refrigerant blends has incorrect component ratios, it will be displayed as
shown in Figure 4-8 A. Press MORE To see the component concentrations. See Figure 4-8 B. Refer to
section 4.11 Printing the Test Results and Channel Data on page 13 to print.

4.10. Measuring Air
The
Pur•Chek™ Pro
offers the ability to measure the presence of air independently during every
test. The built in oxygen sensor will display the percentage of air in all i
dentified
or
identified and
analyzed
refrigerants if there is air in a system or cylinder.
Figure 4-9
A
shows how the LCD will
display air if detected. Pressing ‘MORE’ will display the purity of the refrigerants which were
detected (
Figure 4-9
