16900 Refrigerant Identifier 5
Overview
Sample gas is admitted into the instrument through the supplied sample
hose and presented to the sensing devices. The instrument provides a
digital readout of refrigerant purity, a pass or fail condition, and the
amount of contamination.
A sample is considered to be pure, or passed, if the concentration has
been determined to be 98% or greater by weight of a single refrigerant
(R-134a or R-12). The instrument also provides an indication of
unknown compounds that may be R-22, hydrocarbons, or other
refrigerants commonly used in blended refrigerant types.
Operating instructions are provided to the user through display prompts
to avoid mistakes and erroneous readings.
The Identifier provides the refrigerant technician with knowledge
of refrigerant purity and protection against equipment and air
conditioning system damage resulting from contamination.
