Quizplus · Accepted Answer

Technician A is correct that refrigerant identifiers will identify specific refrigerants by name, including CFC-12 (R-12) and HFC-134a (R-134a). Technician B is incorrect because modern refrigerant identifiers can detect the presence of flammable gases, such as R-290 (propane) and R-600a (isobutane), in addition to other refrigerants. Therefore, neither technician B is not correct.
