An advanced portable refrigerant identifier
  • Analyzes the most common refrigerants quickly and accurately
  • Optional built-in printer for on-the-spot analysis traceability
  • Can “fingerprint” new refrigerants for comparison to future samples


The Pur•Chek™ is an advanced A/C service tool for refrigerant contractors and consolidators in a compact, portable package. It is designed to detect the most common refrigerants – R-12, R-22, R-134a and R-410a – along with non-condensables (air) and hydrocarbons. For other gases, like R-404a or R-507a, you can test your own virgin samples and record the readings for future reference.


Operation is simple – there are only 3 buttons and a full analysis takes only 60 seconds. The Pur•Chek™ can analyze vapor up to 300 psi so it’s safe to use with any refrigerant. Everything comes in a sturdy, hard-shell carrying case to protect your investment and is covered by a 1 year warranty.
