Temperature scale indicates the relationship between pressure and temperature in gas
saturated state.
Differences
2
Change in pressure
2
Change in service port diameter
7. Charge hose for R-410A
Specifications
2
Working pressure 737 psi (51.8 kg/cm

)
2
Rupture pressure 3685 psi (259 kg/cm
2
)
2
Available with and without hand-operate valve that prevents refrigerant from outflow.
Differences
2
Pressure proof hose
2
Change in service port diameter
2
Use of nylon coated material for HFC resistance
8. Weigher for refrigerant charge
Specifications
2
High accuracy
TA101A (for 10-kg cylinder) = ± 2g
TA101B (for 20-kg cylinder) = ± 5g
2
Equipped with pressure-resistant sight glass to check liquid refrigerant charging.
