LB-3308 mask respiratory resistance detector

LB-3308 mask respiratory resistance detector
1、 Overview:

The mask respiratory resistance detector is used to measure the inhalation and exhalation resistance of masks under specified conditions. Suitable for mask manufacturers and national labor protection equipment inspection agencies to conduct relevant testing and inspection of mask products. Compliant with standardsGB2626-2006Technical characteristics of respiratory protective equipment and self-priming filter particle respirator: high clarityLCDLCD display screen; There are two modes available for breath detection and inhalation detection; Large capacity data storage, real-time storage of detection data; Historical data can be printed using a thermal printer; The parameters such as qualified judgment pressure difference and sample number can be set. The test results are for reference only and not the final results.

three Operating procedures:

1. Preparation before sample:

Take four test samples, two without treatment, two according to the standardGB2626-2006 -6.2.1Perform preprocessing. If the tested samples have different numbers, each number should have two samples, one of which is the untreated sample and the other is according to the standardGB2626-2006 -6.2.1Sample after pre-processing.

2. Power supply after connecting the instrument220VGas source3~6Kg.

3. Reset the pressure value of the machine to zero and run it empty. Perform one exhalation test and one inhalation test.

4. Attach the sample onto the head mold.

5. Specific operation of control screen.
