16910 CoolTech ID Plus Refrigerant Identifier
5
Unit Description
The instrument provides the option to purge sample refrigerant sources of air contamina-
tion down to levels set by the user. Air purging is completely automatic and requires no
intervention by the user other than telling the instrument to begin the purging process.
The instrument is supplied complete with R-12 and R-134a sample hoses, an R-134a
adapter fitting to permit sampling of ACME-ported cylinders, a purge vent hose, a power
cord, and all required plumbing housed within a rugged portable case.
Refrigerant Identification
Sample gas is admitted into the instrument through the supplied sample hose and is
presented to the sensing device. The instrument provides the user with direct percent-by-
weight concentrations of R-12, R-134a, R-22, and hydrocarbons. If the sample is deter-
mined to be pure R-12 or pure R-134a, the instrument also provides a direct readout of
the weight percentage of air within the sample. Note that the instrument does not consider
air to be a contaminate, since it can be removed by refrigerant recycling equipment or by
the purging feature of the instrument itself. Since air is not considered a contaminate, it is
possible to read 100% R-12 plus 5% air. The instrument only considers the weights of
refrigerant contaminates in the total mixture.
The instrument interfaces with the user through the use of a 2-line, 16-character, alphanu-
meric display, status indicator lamps, pushbutton communication switches, and an alarm.
Alarm indications are provided to alert the user of instrument fault conditions, potentially
flammable refrigerant presence, and contaminated refrigerant presence. Direct percent-
by-weight concentrations of sample refrigerant are provided on the display, as well as
user directions and prompts. A printer port is supplied with the instrument that interfaces
with most parallel port printers.
