Disposable Medical Mask Respiratory Résistance Tester Application The respiratory résistance tester is suitable for determining the inhalation résistance and exhalation résistance under the régulations of respirators and masks, and for the related testing and inspection of ordinary mask products by the national labor protection equipment inspection agency manufacturer. Standards GB2626-2006, GB /T32610-2016 Features 1. — The instrument consists of an air source that can adjust the flow rate, a human head mold specified in the standard, two intubation Systems for inhalation and exhalation, and a respiratory résistance measurement System. 2. — The flow sensor has high sensitivity and has a very small starting flow. 3. — The flow sensor chip uses a thermal mass flow meter, which does not require température and pressure compensation, ensuring high-precision measurement of the sensor. 4. — Multiple sensors are integrated on a single flow sensor chip, which greatly improves the range ratio of the sensor. 5. — The zéro point stability of the flow sensor is high, with full range and high stability, high accuracy overthe full range, excellent repeatability, low power consumption, low pressure loss and fast response speed. 6. — The data logger uses a graphie dot matrix LCD with a resolution of128 x 64 and a full Chinese interface, which is easy to operate. 7. — the data logger has 4M memory for measurement value recording. 8. — The micromanometer sensor uses a two-wire System, with high accuracy and good stability, it is safe and reliable to use an explosion-proof design.
