摘要
逆扩散型氦质谱检漏仪可以直接用吸枪对冰箱检漏。这种方法检测灵敏度高、操作 简便、无需液氮、无需辅助真空设备、无需排风设备、无毒、无害且能达到A级冰箱检 测标准。
One of the significant quality specifications of the refrigerator is the leakage index of its refrigerant which impacts on the life of the refrigerator directly. If there is leakage on the refrigerator pipe, it will seriously affect the cooling effect and may be hardly repaired or even out of use. The contra-flow helium mass spectrometer leak detector can be used to check the leakage with sniffer probe which has no need for liquid nitrogeN, supplementary vacuum equipment and ventilator. All the detecting processes are non-poisonous and non-pollutant. This equipment will come up to the detecting standard of the A grade refrigerator.
