Application
Used for sterilization and high temperature test of packaging materials (including adhesives and printing ink) in the industries of packaging, plastic films, food, medical units, inspection agency, research institute etc.

Working principle 
The instrument adopts electronic heating method and uses saturated water vapor steam to damp and heat the tested items under pressure condition. After keeping temperature and pressure for a certain period of time, microorganisms are killed and tested items are sterilized.

Counter-pressure method: During the cooling process after sterilization of tested items (bags), the temperature inside the bag remains higher than outside the bag in the tank, and this can cause pressure difference and make the bag burst. To prevent the bursting, we can inject balancing pressure (counter-pressure) air during the cooling process to keep pressure in the tank and eliminate the pressure difference while temperature decreases gradually.

1. Auto temperature rise, auto temperature keeping, auto time count.
2. Counter-pressure method.
3. Unique chamber design, can thoroughly sterilize items, can prevent sample bags from wrinkling or breaking.
4. Water shower cooling and air cooling, with high efficiency and good effect, fast heating and cooling.
5. Control of water level, time and temperature; multiple safety protection against water shortage and over temperature, and auto power off.
6. Intelligent, wholly automatic, digitalized, and real time display of working status, easy to use; the meters integrated into computer module panel, with powerful performance and reliability.
7. Stainless steel body, high capacity, light weight, special design for easy shift to other place, convenient for care and maintenance.
