General

Contamination of refrigerants either in storage cylinders or vehicle air conditioning systems can lead
to component corrosion, elevated head pressures and system failures when utilized by unsuspecting
technicians. The ability of the technician to determine refrigerant type and purity is severely
hampered by the presence of air when attempting to utilize temperature-pressure relations. The
development of various substitute refrigerants further complicates the ability of a technician to identify
refrigerant purity based upon temperature-pressure relationships.
The Neutronics Legend ID™ Refrigerant Analyzer will provide a fast, easy and accurate means to
determine refrigerant purity in refrigerant storage cylinders or directly in vehicle air conditioning
systems. The instrument utilizes non-dispersive infrared (NDIR) technology to determine the weight
concentration of R-1234yf or R-134a refrigerant. Acceptable refrigerant purity as it relates to this
instrument, has been defined by the SAE as a refrigerant mixture that contains 98.0%, or greater of
R-1234yf or R-134a, by weight.
The instrument is supplied complete with an R-1234yf sample hose, an R-134a sample hose (R-12
coupler 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 the
sensing device. The instrument provides the user with a digital display of refrigerant purity. The
instrument only considers the weights of the refrigerant and contaminates in the total mixture. Air is
measured, and displayed, separately. Other contents such as refrigerant oil and dye are not
considered contaminants.
The instrument interfaces with the user via a full color graphic LCD, audio indications and soft key
command buttons. Alarm indications are provided to alert of instrument fault conditions or
contaminated refrigerant presence.
Required SAE Statement (SAE J2912): "If the refrigerant being tested is identified as
contaminated (i.e., less than 98% pure R-1234yf or HFC-134a), any visual percentages displayed
of HFC-134a (R-134a) and/or HFO-1234yf (R-1234yf), outside the design certified value is
informational and may not be accurate"
