FDA Mask Respiration Resistance Tester， Standard Tooling Die With High Storage

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.
