GA-TQ16 Air Permeability Tester
Uvod:
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” del 7: Test method of carbon paper properties.mask test machine mask test machine mask test machine mask test machine mask test machine
Načelo delovanja:
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.
Lastnosti:
1.Uporaba ameriškega računalniškega čipa in koračnega motorja, skupaj z razumno natančnostjo obdelave, da zagotovimo visoko natančnost in ponovljivost opreme. 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) zahteve.
2.Instrument uporablja mikroračunalniško tehnologijo, testni proces je popolnoma avtomatiziran, hitro in natančno. Prikaz rezultatov na zaslonu na dotik, ter funkcije snemanja in obdelave podatkov, z izpisom za tiskanje.
3.Ta instrument ima visoko superiornost. Lahko nastavi višjo razliko tlaka za papir z nižjo prepustnostjo, in nastavite nižjo razliko tlaka za papir z večjo prepustnostjo, enostavno in natančno izmerite rezultat.
4.Test prepustnosti je avtomatski in hiter, in točnost rezultatov testa je zagotovljena. Ta instrument se učinkovito izogiba tem težavam, kot je napačno ravnanje ali nizka stopnja reprodukcije rezultatov testa.
