1. Output display: 7-inch color touch screen
2. Differential pressure gauge: high precision imported digital differential pressure gauge.
3. Flowmeter: high precision imported special flowmeter, high accuracy of flow control.
4. Breathing mode: Two modes of breath detection and inhalation detection can be set.
5. Determination method: automatic constant current control, automatic sample qualification determination.
6. Parameter setting: Parameters such as qualified pressure difference and sample number can be set
7. Instrument composition: it is composed of air source that can regulate the flow rate, human head mold specified in the standard, two tube system for inhalation and exhalation, respiratory resistance measurement system, etc.
8. Flow sensor:
(1) The flow sensor chip adopts thermal mass flowmeter, without temperature and pressure compensation, which ensures the high precision measurement of the sensor.
The measuring range of the flowmeter is 0L/min ~ 100L/min, and the accuracy is ±2%.
In a single flow sensor chip set up a number of sensors, so that the sensor range ratio greatly improved.
(3) The flow sensor has high zero stability, high stability in the full range, high accuracy in the full range and excellent repeatability, with low power consumption, low voltage loss and fast response speed
9. Storage function: There is 4M in the instrument for measuring value record.
10. Micromanometer sensor:
(1) Micromanometer sensor adopts two-wire system, high precision, good stability;
The explosion-proof design is used for safety and reliability
(2) Micro pressure gauge sensor range, zero external continuous adjustable, adjustable damping, no mechanical movable part, less maintenance work.
The range of micromanometer is -1000Pa ~ 1000Pa, and the accuracy is 1Pa.
11. Gas-path conversion: special gas-path conversion element is adopted, which ensures the convenience and speed of conversion between exhalation and inhalation casing system
12. Air pump flow: the pumping volume of the air pump is not less than 40L/min~100L/min
13. Ventilation flow rate: The ventilation volume is constant (85±1) L/min
14. Power supply: AC220V, 50Hz
