If the refrigerant tested is 90% pure or better, the results will be displayed as shown in Figure 9. Should the
refrigerant be less than 90% pure the results will be displayed as shown in Figure 10.
NOTE:
Air is only displayed for R134A and only when the R134A refrigerant concentration is
greater than 90%. “NON” represents non-condensable such as air or another diluting gas.
4.7 Contaminated Blend Refrigerants
The Pur•Chek™ Pro includes the ‘Blend Chek Pro’ feature for determining the presence of R410A. In the event
that the Pur•Chek™ Pro determines that the primary refrigerant in the system or cylinder is likely to be R410A,
the results will display as follows in Figures 10. Pressing the “MORE” button will display the detail screen
shown in Figure 11. If the blend or refrigerant mixture is not recognized, the screen shown in Figure 12 will be

4.8 Pure Blend Refrigerants
The Pur•Chek™ Pro has the ability to identify the following refrigerants: R408A, R409A, R417A, R421A,
R421B, R422A, R422B, R422C and R427A. In addition, the instrument can both identify and analyze the com-
ponent content of pure R134A, R22, R404A, R407C and R410A. Analysis of analyzed pure blend refrigerants
will yield additional data regarding the composition of the refrigerant sample. The Pur•Chek™ Pro will display
the blend refrigerant type as shown in Figure 13. Pressing the “MORE” button will display the detail screen
shown in Figure 14.
