The mask tightness tester is used to test the tightness and tightness of all types of respirators, masks, and gas masks. It is suitable for mask manufacturers and national labor protection equipment inspection agencies to carry out related tests and inspections on mask products.
Applicable standards:
GB 19083-2010 Technical requirements for medical protective masks
Features:
1. Use a particle detector to automatically detect the number of particles inside and outside the mask
2. Destruction and destruction modes, which can realize a variety of test functions
3.7 inch touch screen display, easy to operate
4. Brand-new UI interface design, intuitive operation interface, which greatly improves the operation experience
5. The device comes with a powerful data storage function, which can store up to 50,000 data
6. Mini printer and USB universal data interface, convenient for data output and transmission
7. Intelligent configuration such as overload protection and power-down memory to effectively ensure the safety of users' operations
8. Optional GMP "Computerized System" requires testing software, with user management, authority management, data audit trail and other functions
Test principle:
Under different breathing conditions, measure the particle concentration on the outside and inside of the mask, and calculate the mask fit factor based on the results.
Technical characteristics:
1. Simple operation and convenient use;
2, stand-alone operation type, without external connection to a computer;
3. Optional mask sample selection adapter, allowing various mask fit detection;
4. The color touch screen can be operated with fingers or pens;
5, FitPro+TM tightness test software, can automatically complete the test;
6. Use an external computer to generate a report and print a tightness test card;
7. Use the microscopic particles in the ambient air to calculate the tightness factor of the mask;
8. Provide interactive training tools for initial and follow-up training.
