2
)
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.
