FT-1 lung ventilation meter how to price

FT-1-meter one-lung ventilation use and features: This instrument from the lungs through the low Reynolds number vortex flow sensors, microcomputer and mask components. Some have resistance  wide range, measurement accuracy. It can be widely used to determine the metallurgical, mining, construction, machinery, shipbuilding, transportation, coal and other industries dust hazards and physical strength grade level classification. Also the physical health, science and sports management instrument used for scientific research. The main technical indicators: Measuring range: lung can gas: 6-80 liters steady flow: 8-240 liters ventilation error: ≯2.5% steady flow error: ≯2% time error: ≯10 seconds / hour Inlet: Inhaled: breathing resistance: ≯49Pa (flow of 30 liters / minute) expiratory resistance: ≯29Pa (flow of 30 l / min) display range: 0.01-9999 display options: total flow (liters); total time (in seconds); The average flow rate (liters / min)
