Overview
DESCRIPTION OF THE 16900 IDENTIFIER
Contamination of refrigerant in air conditioning systems or storage
cylinders can lead to component corrosion, component destruction,
elevated system head pressure, and system failures when used by
unsuspecting technicians. The ability of a technician to determine
refrigerant type and purity is severely hampered by the presence of
air when attempting to use pressure-temperature relationships. The
development of substitute refrigerants further complicates refrigerant
identification and purity determination based on pressure-temperature
relationships.
The Refrigerant Identifier provides a fast, easy, and accurate means
to determine refrigerant type and purity in refrigeration systems and
refrigerant storage cylinders. The instrument utilizes a combination of
infrared and chemical fuel cell technologies to determine purity and
contamination levels of refrigerant R-12 and R-134a, as well as air
concentrations in both refrigerant types.
The instrument is supplied in a rugged, hand-held, injection-molded,
nylon case housed in a corrugated storage case. The storage case will
also house all accessories supplied with the instrument: R-12 sample
hose, R-134a sample hose, R-134a tank adapter fitting, battery power
adapter, and wall power adapter.
