 Single-metal composite film gas sampling bags Tsui 
 Double metal composite membrane gas sampling bags Tsui 
 Configuration instructions: single metal nozzle assembly of composite membrane gas sampling bags a metal nozzle (Metal Fitting), a sample pad. Double metal composite membrane gas sampling bags nozzle assembly of two metal nozzle, a sample pad. Guide: 
 1, the inflation pressure of not more than 6KPa, visual observation of the air bag full muster, but not taut with your fingers press. 2, the metal nozzle and instruments, devices should use the appropriate diameter latex tube, silicone tube transition, and the use of tube clip clamp. 3, flexible sampling pad for needle sampling or vacuum. When the needle set aside immediately after the sampling pad a little pinch force, in order to facilitate barbed mouth closed, to ensure air tightness. 4, the metal nozzle needle can be fully deflated and vacuum sampling. Bi-metal nozzle replacement easier. 5, the metal nozzle made of chrome-plated copper alloy can be filling non-corrosive inorganic and organic gases. 6, standard gas filling or sampling, to use the pre-gas replacement 3 times. 7, temperature, -20 ℃ - +60 ℃, 8, storage and use, away from open flames and high temperature, to avoid sharp punctured. Specifications: 0.5L, 1L, 2L, 3L, 4L, 5L, 8L, 10L, 15L, 20L, 30L, 40L, or custom. Features: simple operation, stable performance, low price
