Meet the following criteria
QC/T 795.2-2007 Automotive Air Conditioning Filter Part 2: Gas Filtration Test
Air flow | Flow range: (100~600)m³/h. |
Measurement accuracy: 1.5 level. | |
Intake resistance (measured by pressure transmitter) | Range: (0~10)kPa. |
Accuracy: ±0.1%. | |
Contamination intake pressure measurement (measured by pressure transmitter) | Range: (0~1)MPa. |
Accuracy: ±0.1%. | |
Intake system | The intake air is filtered by a HEPA high efficiency filter to remove suspended particulates introduced into the air. |
The pipeline is made of corrosion-resistant stainless steel, and the air inlet port is rectified by a honeycomb rectifier to ensure a uniform flow field. | |
Contaminant intake air mass flow control (for n-butane) |
The mass flow controller is used to accurately measure and control the mass flow of gas. Full-scale flow range: 5SCCM~30SLM. Control range: (2~100)%FS. Accuracy: Ordinary type When ≤10SLM, ±1%FS. When >10SLM, ±2%FS. Repeatability: ±0.2%FS. |
Gas concentration analyzer |
n-Butane test Measuring range: (0~100)ppm. Resolution: 0.01ppm. Accuracy: ≤±3%FS. Toluene test Measuring range: (0~100)ppm. Resolution: 0.01ppm. Accuracy: ≤±3%FS. |
