Protective mask airtightness tester respirator as a respiratory protection equipment required in the field of medical protection, the type of mask can be mainly divided into disposable masks, replaceable half masks and full masks, the various properties of the mask for personal safety protection is also crucial, the air tightness effect of the mask will also directly affect the user's life and health, testing and evaluating the advantages and disadvantages of the air tightness of
the mask is very necessary.
The mask airtightness tester produced by the company is designed according to the requirements of the standard: GB2626-2019 "Respiratory Protection Products Self-Suction Filter Anti-particle Respirator" to detect the airtightness
of the mask.
First, the principle: the mask is matched on the test head mold according to different specifications of selection, seal the suction valve, wet the exhalation valve, start the vacuum pump, so that the pressure inside the mask reaches -1000pa-1000pa, stop pumping, start timing, observe and record the pressure change value
in the mask.
Second, technical parameters 1, buffer capacity is not less than 5 liters 2, micro pressure difference metering range: -1000Pa ~ 1000Pa, accuracy 1%, resolution 1Pa3, vacuum pump pumping speed approx: 2L / min -30L / min according to the requirements can be arbitrarily customized 4, flow metering process: 0 ~ 100mL / min
.
According to the requirements can be arbitrarily customized 5, the overall size: 500×450×620mm according to the requirements can be arbitrarily customized 6, weight: 30kg7, power: AC220V 50Hz 150W8, workstation: 4 stations or more stations; 9, control system: PLC independent control of each station; 10, the shell is made of 1.
5 thick plate, surface spray plastic anti-static; 11, Weilun Tong 7-inch touch screen, Chinese and English switching interface; 12, mask molding according to customer requirements customization or customers choose other molding; 13, the appearance of the design value is high, cost-effective; 14, warranty period of one year; 15, after-sales service center 24-hour service, 8 hours to give and answer the processing method; 16, factory direct sales, reasonable price, after-sales guarantee, after-sales time; 17, pressure difference range: -100pa-1000pa according to the requirements can be optional other ranges
