For ordinary consumers, the most practical feeling about the breathing resistance of masks is "whether it is stuffy or not. Many children can't wear a three-dimensional mask with better protective effect.
This is the reason, because although the protective mask has high filtration efficiency, it also has great respiratory resistance, especially in summer, it will be very boring to wear.
The Respiratory Resistance Tester is used to measure the inspiratory and expiratory resistance of meltblown filter materials under specified conditions. It is suitable for meltblown filter material manufacturers and national labor protection articles inspection agencies to carry out relevant tests on meltblown filter material products.
Product features:
1. The instrument consists of an air source with adjustable flow rate, a standard human head model, two sets of pipeline systems for inhalation and exhalation, and a respiratory resistance measurement system.
2. The flow sensor has high sensitivity and very small initial flow.
3. The flow sensor chip adopts thermal mass flowmeter without temperature and pressure compensation, which ensures the high-precision measurement of the sensor.
4. Multiple sensors are integrated on a single flow sensor chip, which greatly improves the range ratio of sensors.
5. The flow sensor has high stability at zero point, high stability in full range, high precision in full range, excellent repeatability, low power consumption, low voltage loss and fast response speed.
6. The data recorder adopts graphic dot matrix liquid crystal with resolution of 128×64, with all Chinese interface and convenient operation.
7. There is 4M memory in the data recorder for recording measured values.
8. The micro-pressure meter sensor adopts two-wire system with high precision and good stability; The explosion-proof design is safe and reliable.
9. The measuring range and zero point of the micro-pressure meter sensor are continuously adjustable externally, the damping is adjustable, there is no mechanical moving part, and the maintenance workload is less.
10. The whole instrument adopts special air circuit conversion element, which ensures the convenient and quick conversion of two sets of pipeline systems of exhalation and inhalation.
Technical characteristics
High-definition LCD screen; Electronic flowmeter with high flow control accuracy; Automatic constant current control, automatic sample qualification judgment; Two modes of exhalation detection and inhalation detection can be set. Large capacity data storage, real-time storage of detection data; Historical data can be exported through U disk or printed by thermal printer. Parameters such as pressure difference and sample number can be set.
The whole Respirator Breathing Resistance Tester equipment is easy to operate, one person can complete the operation, and the data is accurate. The most important thing is to operate intelligently to avoid data deviation caused by human operation.
Automatic protection for fault detection
It is applicable to the relevant detection and inspection of common melt-blown filter materials, dust-proof melt-blown filter materials, medical melt-blown filter materials and smog-proof melt-blown filter materials by national labor protection articles inspection institutions and melt-blown filter material manufacturers.
Breathing valve airtightness tester, expiratory resistance machine Equipment principle: Breathing valve airtightness tester, expiratory resistance machine is mainly composed of test head die, breathing pipe, pressure measuring tube, differential pressure sensor, flowmeter, regulating valve, three-way valve, vacuum pump and air compressor.
