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 elements, such as air or another dilut-
ing gas.
4.5 Blend Refrigerants
The Pur•Chek™ includes the ‘Blend Chek’ feature for determining the presence of R410A. In the event that
the Pur•Chek™ determines that the refrigerant in the system or cylinder is likely to be R410A, the results will
display as follows in Figures 11. Pressing the “MORE” button will display the R410A screen shown in Figure 12.
If the Blend is not recognized, the screen shown in Figure 13 will be displayed. Note: Please refer to Section 2,
