Spirograph SMP-02-"R-D"/1 with integrated thermal printer

The spirograph SMP-02-"R-D"/1 is used in functional diagnostics departments, wellness centers, medical services of enterprises (conducting medical examinations), in sports, aerospace medicine to monitor the effectiveness of therapeutic and rehabilitation measures in pulmonology, monitoring for asthma, and for medical and labor expertise.

The spirograph sensor provides air flow measurement when the patient inhales or exhales.

The sensor converts the air flow into an electrical signal by ultrasonic method.

The ultrasonic measurement method has a high resolution (250 measurements per second), which guarantees reliable determination of all measured parameters with the highest accuracy.

When using the ultrasonic flow measurement method based on digital technologies, auxiliary flow assessment parameters (for example, differential pressure) are no longer required. The gas flow and volume are calculated based on measuring the travel time of an ultrasonic pulse in the forward and reverse directions. The time difference between the forward and reverse directions is proportional to the air flow velocity.
