R-134a Proper use
2 Proper use
The analysis module determines the refrigerant analysis for vehicle air
conditioning systems with R-134a refrigerant. The device is designed for
commercial use.
The analysis module may only be operated by personnel who have the
expertise required for servicing air conditioning systems.
3 Technical description
The analysis module determines the degree of purity of R-134a. It is suit-
able for displaying the percentages of the following refrigerants:
R-134a
R-12
R-22
HC (hydrocarbons, e.g. isobutane or propane)
Air
Unknown
The analysis module creates an overview of the percentage shares of the
individual gases. A possible percentage of air is calculated (e.g. 100 %
pure R-134a refrigerant + 10 % air). This overview is output by the display
and the AirCon Service Centre printer.
