Product Introduction It can be used to detect or test internal pressure  for soft package like  PET bottles or aluminum cans after liquid nitrogen dosing.  The device can quickly detect and remove unqualified products and provide sound and light alarm, allowing users to monitor if front-end equipments work properly and aviod unqualified products flowing to market. When continuous substandard products being kicked out appears, it is a single that there is malfunction  happening at the front-end equipment.  That is to say, it can be set to  find the front-end equipment working status to reduce the loss. In addition, it  is also as as monitor to the detect the volume of liquid nitrogen and adjust if necessary. The device has capability of determining whether the internal pressure is qualified instead of destroying the pakcage.
