Abstract:
Objective To develop an instrument for automatic testing of airtightness of the equipment and facilities in biosafety laboratory using pressure decay method with an aim at improving testing efficiency.Methods On the basis of the characteristics of the pressure decay method and the equipment performance in the biosafety laboratory,the PLC and touch screen and etc,industrial control instrument was employed for designing the structure and components.By programming PLC and touch screen the intended functions were achieved.Results This developed instrument could be used for automatic and multi-channel air tightness testing in parallel,as well as for monitoring and recording the pressure and temperature data of the equipment in real time.Conclusion By using the developed instrument,the testing cycle,and the manpower and material resources input can greatly be reduced.It is presumed that the instrument can be used for testing the airtightness of facilities and equipment in biosafety laboratory.
