GA-TQ16 Air Permeability Tester
Invoering:
GA-TQ16 Carbon Paper Air Permeability Tester adopts a new technology, which is specially used to test the air permeability of carbon paper for fuel cell. The test standard conforms to GB/T20042 “Proton exchange membrane fuel cell” deel 7: Test method of carbon paper properties.mask test machine mask test machine mask test machine mask test machine mask test machine
Working Principle:
According to the principle of pressure difference method, place the pre-processed sample between the upper and lower test heads. A constant pressure difference is formed on both sides of the sample. Under the action of pressure difference, the air flows from the upper test head through the sample to the lower test head, and the air permeability of the sample is calculated according to the area, pressure difference and flow rate of the sample.
Functies:
1.Using US computer chip and stepper motor, coupled with reasonable design precision machining, to ensure the equipment is of high accuracy and repeatability. The calibration of the pressure sensor and flow is traceable.Using imported high-precision micro-differential pressure sensor, the actual measurement error can be less than 0.2Pa, far higher than the standard (±2Pa) requirements.
2.The instrument uses microcomputer technology, the test process is fully automated, fast and accurate. Touch-screen display results, and data recording and processing functions, with printing output.
3.This instrument has the high superiority. It can set the higher pressure difference for the paper with the lower permeability, and set the lower pressure difference for the paper with the higher permeability, easily and accurately measure the result.
4.The test of the permeability tester is automatic and fast, and the accuracy of the test results is guaranteed. This instrument effectively avoids these problems such as mishandling or low reproduction rate of test results.
