European standard EN149-7.16 Breathing resistance test wearing a mask
European Standard EN149-7.16 Mask Respiratory Resistance Tester
【Scope of application】: Used to measure the inhalation and exhalation resistance of respirators and masks under certain conditions. It is suitable for the relevant testing and inspection of ordinary masks, dust masks, medical masks and anti-fog masks by national labor protection equipment inspection agencies and mask manufacturers KN particulate respirators and related products are tested.
Compliance with standards: EN149-2001 7.16 etc.
1. The instrument uses intelligent intelligentcolor screen control, automatic measurement mode, automatic measurement of inhalation and exhalation, printing of data statistics.
2. Adopt self-cleaning air source filtration device, the full name is silent mode, no external air compressor or air pump is required.
3. It is measured by a high quality digital flow sensor and has a very low initial flow.
4. Micro pressure gauge sensor range, the zero point can be continuously adjusted from the outside, damping can be adjusted, there is no mechanical moving part, and it is high.
5. Fully automatic measurement mode, no need to manually adjust the flowmeter, high data reproducibility.
6. Using a standard head mold, the mask sample is sealed and fixed in a sealed and airtight manner, making the test convenient.
