Fully automatic respirator resistance tester

Breathing Resistance tester

[Scope of application] : It is used to measure the inhalation resistance and exhalation resistance of respirators and masks under specified conditions. It is applicable to the relevant testing and inspection of common masks, dust masks, medical masks and anti-haze masks by national labor protection products inspection institutions and mask manufacturers, and can be used for the testing of KP and KN particle respirators and related products by production enterprises, scientific research institutions and third-party testing institutions.

[Meeting the standards] :

EN149/8.9

[Instrument characteristics] :

1. The instrument adopts intelligent color screen control, automatic measurement mode, automatic measurement of inhalation and exhalation, statistical data printing.

2. Adopt self-cleaning air source filter device, full name silent mode, no need for external air compressor or air pump.

3, the use of high-precision digital flow sensor measurement, there is a very small starting flow.

4, micro pressure gauge sensor range, zero external continuous adjustable, adjustable damping, no mechanical movable part, high precision.

5, automatic measurement mode, no need to manually adjust the flowmeter, high data reproducibility.

6. Adopt standard head mold, mask sample seal and leak proof fixation method, which is convenient for testing.
