Masks Bacterial Filtration Efficiency (BFE) testing equipment test procedure:   1. Start the instrument and perform air cleaning.   2. Install the Staphylococcus aureus solution, start the peristaltic pump and supply the solution to the tip of the sprayer.   3. Install the mouthpiece sample in A-way, B-way as positive QC, and install the flat dish into the Anderson sampler.   4. Set instrument parameters.   5. Remove the sampled flat dishes, mark the layer number and place them in the incubator to count the positive pore count values for each layer of the plate. 6. Calculate the result, BFE=(positive QC average - sum of experimental sample counts)/positive QC average*100%  

Protective Mask Tensile Testing Machine purchase attention matters Protective Mask Tensile Testing Machine purchase precautions: 1, first of all, should consider the need to test the range of material tension. The difference in the range of tension determines the different sensors used, which also determines the structure of the Protective Mask Tensile Testing Machine, but this has little impact on the price. For general flexible packaging manufacturers, the tension range of 100 Newton is sufficient. Therefore, it is also decided to use a single-arm type can be. The structure corresponding to the single-arm type is the door type structure, which is adapted to a relatively large pull, such as a ton or more. So flexible packaging manufacturers basically do not use. 2, the test stroke problem. According to the performance and requirements of flexible packaging film needs to be tested, the stroke in 600-800mm can be. Material elongation of more than 1000% can choose to travel 1000 or 1200m...

Masks Bacterial Filtration Efficiency (BFE) Tester (BFE) testing equipment maintenance and care:   1. Non-working test time, please cut off all power. If this tester is not used for a long time, it should be powered on regularly to ensure that the instrument is working properly, usually once a month, for not less than 30 minutes each time. Can be run in the aerosol chamber pressure balance state for 30 minutes;   2. The power cord may have poor contact or disconnection after long-term use, each use before the overhaul, to ensure that the power cord is not damaged, cracks, disconnection phenomenon; 3. Prohibit direct sunlight to the glove, so as not to accelerate aging.   4. The detector with high efficiency filter is a consumable item, under normal circumstances need to be replaced once a year;   5. When there are water droplets in the water splitting filter, please loosen the knob at the lower end of the water splitting filter and release the water, after emptying, ...
