The Bacharach Pur•Chek™ HVAC/R refrigerant identifier features a quick 60 second test time with its large display and optional built-in printer for precise measurement of refrigerant purity. The product uses its non-dispersive infrared (NDIR) technology for determination of weight concentrations of R12, R134A, R22, hydrocarbons, and air. A ‘Blend-Chek’ analytical software is also in use for an accurate indication of the presence of R410A blend refrigerant. Moreover, the Advanced Refrigerant Identifier is a service tool for contractors and consolidators in general.
