1 - | Temperature scale for refrigerant R134a CF3–CH2F or CH2F–CF3 |
The pressure gauges can have one or more temperature scales in addition to the pressure scale. The values of the scale for R134a are assigned to the relevant vapour pressure table. |
As various refrigerants build up different vapour pressures at the same temperature, every temperature scale is marked for the corresponding refrigerant. |
