Mask respiration resistance tester
Detection principle
· The instrument consists of a breathable air source with adjustable flow rate, a human head model specified by the standard, an inhaling and exhaling circuit system, and a respiratory resistance measurement system.
· Adopt special air path conversion elements to ensure that the exhalation and inhalation two tube systems are easy and fast to replace.
· Digital display of breathing resistance, with zero point correction, accuracy correction and over-range alarm function.
· Adopt standard flow meter, flow control accuracy is high.
· Computer control and acquisition system realizes real-time detection and output of pressure control, breathing frequency control and breathing resistance test data.
Applicable standards
· GB 2626-2019 Respiratory protective equipment self-priming filter anti-particulate respirator
· GB / T 32610-2016 Technical Specifications for daily protective masks.
