General
Contamination and mislabelling of refrigerants either in storage cylinders or 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 substitute refrigerant
blends can also introduce a flammability hazard to the technician and the ultimate end user of the air
conditioning system.
The YELLOW JACKET 68940 Refrigerant Analyzer provides a
fast, easy and accurate means to
determine refrigerant purity in refrigerant storage cylinders or directly in air conditioning systems.
The instrument utilizes non-dispersive infrared (NDIR) technology to determine the weight
concentrations of multiple refrigerant types. Refrigerant purity is displayed on the LCD Screen and
the user must determine acceptable levels of purity based on their recovery or use standards.
The instrument is supplied complete with a
¼” Flare Vapor Sampling Hose, a High Pressure Liquid
Sample Trap Assembly, a 100-240 VAC power transformer, built in Lithium Iron Phosphate battery,
thermal printer, and all required plumbing housed within a rugged, portable, storage case.
Testing occurs when sample gas is admitted into the instrument through the supplied sampling hose
configurations and presented to the sensing device. The instrument provides the user with direct
percent by weight concentrations.
The instrument interfaces with the user via a LCD graphic display, status indicator
LED’s, and push
button communication switches. Direct percent by weight concentrations of the sampled refrigerant
are provided on the display as well as user directions and prompts. An on-board printer is provided
to print an on-the-spot analysis report.
The YELLOW JACKET 68940 Refrigerant Analyzer Refrigerant Analyzer provides the refrigerant
technician with
excellent knowledge of refrigerant type and purity as well as protection against
refrigerant contamination and potential flammability.
