ZY-YQ14Mask respiratory resistance tester

Compliant with standards:GB 2626-2006、 GB/T 32610-2016

Technical parameters:

1.The range and zero point of the micro pressure gauge sensor are continuously adjustable externally, with adjustable damping and no mechanical movable parts, resulting in less maintenance workload. The range of the micro pressure gauge is -1000Pa to 1000Pa, with an accuracy of 1Pa.

2The entire instrument adopts special gas path conversion components, ensuring convenient and fast conversion between the exhalation and inhalation pipeline systems.

3The pumping capacity of the air pump shall not be less than 40L/min~100L/min

4The ventilation rate remains constant at (85 ± 1) L/min

5Power supply:AC220V，50Hz
