LFY-722 Respiratory Tube Air Resistance Tester

Main application
This instrument is applicable to the air flow resistance of breathing devices, breathing tubes and humidifiers, nebulizers for anesthesia and respiratory equipment accessories, including disposable and reusable breathing devices and breathing tube connectors. Principle
The flow resistance is tested by measuring the pressure increase through the breathing device, breathing tube, or breathing tube with a connector.
Instrument features
1. It can provide an air flow rate of no less than 100L/min;
2. Flow control device: Equipped with a high-precision flow sensor to measure the air flow rate, with an accuracy of 2.5%;
3. Pressure measurement device: Equipped with a high-precision micro-pressure sensor, with a range of 0-1000Pa and an accuracy of ±10Pa;
4. Equipped with a standard breathing tube interface for easy replacement of the sample;
5. Uses a liquid crystal to display pressure and flow in real time, with parameter and alarm point settings on the panel;
6. Power supply: 220V, 50Hz.
Technical specifications
1. Uses an air compressor as the gas source to supply gas to the instrument, without being limited by the space of the test site;
2. Equipped with a high-precision pressure gauge to display the pressure value of the gas path. The accuracy is ±10Pa;
3. Timing range: 0-99.99s, accuracy: ±0.01s;
4. Special sample pipeline connector.
5. Power supply: AC220V, 50Hz
