NovaStar, QT138, Tester for Mask Dead Space, AC220V 50Hz, CO2 Flowmeter 0-100L/min (New)

Description

Overview
1. Scope of application: used to detect the dead space performance of masks and respirators under specified conditions.
2. Related standards: GB2626
Instrument Characteristics
1. The test process is controlled by a computer program to achieve automatic detection, automatic recording and automatic calculation of changes in the concentration of carbon dioxide inhaled gas during the entire test process.
2. There is no need to adjust the breathing frequency and breathing volume during the test; you can change the breathing frequency and breathing volume through simple parameter setting operations on the computer, making adjustment very convenient and accurate.
3. The one-way valve that controls the breathing channel is automatically controlled by the ventilator using a solenoid valve group, which is completely synchronized with the action of the ventilator, making the test results more accurate.
4. The data of the test process is automatically saved in the computer, and the test report is automatically generated.
Technical Parameters
1. Breathing frequency modulation: 10 to 40 times/min, adjustable; standard is 20 times/min.
2. Tidal volume range: 0.5 to 3.0 L/min, adjustable.
3. The volume fraction of CO2 is 5.0 ± 0.1%.
4. CO2 flowmeter: 0 to 100 L/min.
5. CO2 analyzer range: 12% to 70%, accuracy is not less than 0.1%.
6. Wind speed: 0.5 m/s.
7. Breathing tidal volume: 1.5 L.
8. Power: AC220V 50Hz.
