Protective mask airtightness tester Medical site In order to prevent infection, and when working in labor, it is necessary to ensure that workers are protected from the injury of inhalable dangerous substances in the workplace, and must wear masks and other respirators
during operation.
Select a respirator such as a mask in combination with your own facial features, and evaluate the tightness between the respirator such as a mask and the face, and check whether there are gaps or leaks that
put workers at risk.
Protective mask airtightness tester to ensure that it provides good protective performance
.
Widely used in hospitals, manufacturing plants, production sites, fire workplaces and other testing
institutions.
The mask airtightness tester produced by Shanghai Chengsi Intelligent Technology Co.
, Ltd.
is designed according to the requirements of the standard: GB2626-2019 "Respiratory Protection Products Self-priming 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 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 is high, cost-effective; 14, warranty period of one year; 15, pressure difference range: -100pa-1000pa according to the requirements can be optional other ranges
