Manual Part Number:5-06-7000-80-0Manual File:012476 Rev. APage 1-81 INTRODUCTION AND OVERVIEWGeneralContamination of refrigerants either in storage cylinders or vehicle air conditioning systems can leadto component corrosion, elevated head pressures and system failures when utilized by unsuspectingtechnicians. The ability of the technician to determine refrigerant type and purity is severelyhampered by the presence of air when attempting to utilize temperature-pressure relations. Thedevelopment of various substitute refrigerants further complicates the ability of a technician to identifyrefrigerant purity based upon temperature-pressure relationships.The Neutronics Legend ID™ Refrigerant Analyzer will provide a fast, easy and accurate means todetermine refrigerant purity in refrigerant storage cylinders or directly in vehicle air conditioningsystems. The instrument utilizes non-dispersive infrared (NDIR) technology to determine the weightconcentration of R-1234yf or R-134a refrigerant. Acceptable refrigerant purity as it relates to thisinstrument, has been defined by the SAE as a refrigerant mixture that contains 98.0%, or greater ofR-1234yf or R-134a, by weight.The instrument is supplied complete with an R-1234yf sample hose, an R-134a sample hose (R-12coupler sold separately), a 100- 240 VAC power transformer, built in Lithium battery, thermal printer,and all required plumbing housed within a rugged, portable, storage case.Sample gas is admitted into the instrument through the supplied sample hose and presented to thesensing device. The instrument provides the user with a digital display of refrigerant purity. Theinstrument only considers the weights of the refrigerant and contaminates in the total mixture. Air ismeasured, and displayed, separately. Other contents such as refrigerant oil and dye are notconsidered contaminants.The instrument interfaces with the user via a full color graphic LCD, audio indications and soft keycommand buttons. Alarm indications are provided to alert of instrument fault conditions orcontaminated refrigerant presence.Required SAE Statement (SAE J2912): "If the refrigerant being tested is identified ascontaminated (i.e., less than 98% pure R-1234yf or HFC-134a), any visual percentages displayedof HFC-134a (R-134a) and/or HFO-1234yf (R-1234yf), outside the design certified value isinformational and may not be accurate"
