The ultimate portable refrigerant analyzer
  • Vapor or liquid sample analysis of over a dozen refrigerants
  • Built-in printer for on-the-spot analysis traceability
  • Can “fingerprint” new refrigerants for comparison to future samples


The Pur•Chek™ Pro is a powerful refrigerant analyzer capable of identifying more than a dozen refrigerants, all in a compact, portable package. Refrigerants that can be identified and analyzed include R-22, R-134a, R-404a, R-407c, R-410a and hydrocarbons. There are even more refrigerants that can be identified, including R-12, R-32 and others. For new refrigerants not programmed into the software, you can test your own virgin samples and “fingerprint” the readings for future reference.


Operation is simple – there are only three buttons and a full analysis takes only 60 seconds. The Pur•Chek™ Pro can analyze vapor or liquid, making it ideal for any situation. Everything comes in a sturdy, hard-shell carrying case to protect your investment and is covered by a 1 year warranty.
