4.7. Contaminated Blend Refrigerants

he Pur•Chek™ Pro includes the ability to detect and analyze the composition of many common R400

Series refrigerants in addition to R134a, R22 and hydrocarbons. In the event that the Pur•Chek™ Pro

determines that the primary refrigerant in the system or cylinder is one of the recognized measurable

refrigerants, a results screen similar to Figure 4-5A will be displayed. Pressing the MORE button will

display a detail screen similar to Figure 4-5B. If the blend or refrigerant mixture is not recognized,

Figure 4-5C will be displayed.

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 component 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 4-6A. Pressing the MORE button will

display the detail screen shown in Figure 4-6B.

4.9. 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 R404A, R407C and R410A. If one of

these refrigerant blends has incorrect component ratios, it will be displayed as shown below in

Figure 4-7A. To see the component concentrations (similar to Figure 4-7B) press MORE.
