Product Brief The N600C Carbon Paper Air Permeability Rate Tester is designed and developed in accordance with GB/T 20042.7-2014. Adopting the differential pressure method as its testing principle, it is professionally used for measuring the air permeability rate of various types of carbon paper for proton exchange membrane fuel cells (PEMFC). Testing Principle Based on the differential pressure method, the sample is placed between two fixtures, forming a constant differential pressure on both sides of the sample. Driven by the differential pressure, gas flows from the high-pressure side through the sample to the low-pressure side. The air permeability rate of the carbon paper is calculated based on the transmission flow rate, sample thickness, test area, and test differential pressure.

GBD-L2 falling dart impact tester is suitable for testing materials such as plastic film or sheet and steel plate coating with a thickness of less than 1mm. Under a given height of free falling dart impact, it can measure the energy (in Quality to express results) of plastic films,thin section specimens and other materials. Through the impact resistance test, it can prevent the packaging surface from being damaged when the packaging material is impacted or dropped due to insufficient toughness of the packaging material, and effectively avoid the product from being damaged due to impact or falling in the circulation link. It can be used in scientific research, teaching, industrial and mining enterprises, laboratories, research institutes and quality supervision departments.
