Evaporation Pressure and Temperature Test This manifold gauge can test the maximum pressure when the refrigerant changes from liquid to gas. The lowest temp when the liquid becomes gaseous.(The lower the pressure and temp of the evaporation are, the more efficient the refrigeration cycle and the greater the refrigeration capacity will do.) | Condensing Pressure&Temp Test This air pressure gauge can test the minimum pressure when the refrigerant changes from gas to liquid, and the maximum temp when the gas changes to liquid. (The lower the pressure and temp of condensation are, the higher the efficiency of the refrigeration cycle and the greater the refrigerant capacity will do.) | Pressure Leakage Test Calculate the pressure difference between the initial test pressure and the second test pressure to determine whether the refrigerant leaks. |

If the displayed temperature is 100 ℃ ± 3%, it is normal. |
