The mask breathing resistance detector is used to measure the inhalation and expiratory resistance of masks under specified conditions. It is suitable for mask manufacturers and national labor protection equipment inspection agencies to conduct relevant testing and inspection of mask products. In line with the standard GB2626-2006 respiratory protection products, self-priming filter anti-particulate respirator technical features High-definition LCD liquid crystal display; can be set to two modes of exhalation detection and inhalation detection; large-capacity data storage, real-time preservation of test data ;Historical data can be printed through thermal printer; parameters such as qualified judgment pressure difference, sample number can be set. Test results are for reference only.

 

Operating procedure:

1. Preparation before sample:

 

Four test samples were taken, two were not treated, and two were pretreated according to the standard GB2626 2006-6.2.1. If the tested samples have different numbers, there should be two samples for each number, one is the untreated sample, and the other is the pre-treated sample according to the standard GB2626-2006-6.2.1.

 

2. After connecting the instrument, the power supply is 220V, and the gas source is 3~6Kg.

 

3. Clear the pressure value of the machine to zero and run the expiratory test once and the inhalation test once.

 

4. Put the sample on the head mold.

 

5. The specific operation of the control screen.
