infusion bag iv bag Leak and Seal Strength testing instrument; is applicable in the quantitative measurement of leak, heat seal strength, heat seal quality, and burst pressure of each heat seal edges of the flexible packages (of course infusion bag, iv bag is included) that are made using heat seal and adhesive processing, as well as sterilized packages; the quantitative measurement of leak performances of all kinds of plastic pilfer-proof closures; the quantitative measurement of the unitary airproof, compression resistance strength, cap body joint strength, cap disengaging strength, seal strength of edge and butting strength of various flexible tubes. It can also provide evaluation and analysis for the compression and burst resistance strength of the materials of flexible packaging bags, the torsional airproof index of cap, the cap joint and disengaging strength and the stress strength; as well as the airproof performances, the compression resistance performance and the burst resistance character of unitary bottle, etc.    Features Micro-computer control, LCD display Menu interface, PVC operation panel Positive pressure method Adjustable testing range Two testing modes: expansion restraining and expansion non-restraining Multi-testing methods of burst test, creep test and creep-to-failure test One-key testing process Automatic statistical analysis Mini-printer RS232 port Network transmission interface for LAN data management and Internet data transmission Technical Indexes Test range: 0~250kPa; 0~36.3 psi (standard) 　　　　　0~400kPa;0~58.0psi (optional) 　　　　　0~600kPa;0~87.0 psi (optional) 　　　　　0~1.6MPa;0~232.1psi (optional) Pressure of compressed air: 0.4MPa~0.9MPa (compressed air should be provided by users) Compressed air inlet size: Φ8mm polyurethane pipe
