Contamination of refrigerants in 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 deter-
mine refrigerant type and purity is severely hampered by the presence of air
when attempting to utilize temperature-pressure relations. The develop-
ment of various substitute refrigerants further complicates the ability of a
technician to identify refrigerant purity based upon temperature-pressure
relationships. The substitute refrigerant blends can also introduce a flam-
mability hazard to the technician and the ultimate end user of the vehicle air
conditioning system.
The Mini ID Refrigerant Identifier will provide an easy and accurate means to
determine if the R134a refrigerant in vehicle air conditioning systems is of
suitable purity. The instrument utilizes non-dispersive infrared (NDIR) tech-
nology to determine the weight concentrations of refrigerant types R12,
R134a, R22, as well as, hydrocarbons and air. Refrigerant purity is auto-
matically determined for refrigerant R134a by the instrument to eliminate
human error.
The instrument is supplied complete with a R134a sample hose, a 12 VDC
power cord and all required plumbing housed within a rugged, portable in-
strument.

The Mini ID is an economical instrument designed to provide a “PASS” or
“FAIL” indication for R134a Purity. The product will also indicate if an ex-
cess amount of non-condensable gas (air) is present in the system. Excess
“air” will cause poor cooling performance and can be easily corrected by
simply recovering the refrigerant, evacuating the system and recharging the
vehicle. The Mini ID uses a simple hand pump to purge refrigerant from the
sample cell in order to calibrate the instrument. LED’s provide the user with
easy to understand status indicators. Flashing LED’s require user action
while solid LED’s indicate the instrument is performing a task.
The unique brass filter, located between the Coupler and Sample Hose, pro-
vides excellent protection from oil contamination by trapping the oil at the
coupler and preventing it from entering the instrument. If the instrument
continually gives excess air messages, this is an indication that the filter has
been compromised by oil and the filter must be changed.
