The Duo Control blood pressure monitor from Veroval impresses with its large display. This makes it easier to read the measured values and the ambient temperature. Thanks to the patented "Secure fit" cuff, cuff seat check and rest indicator, correct measurement is simplified. The device measures with 2 methods: The Korotkoff microphone measurement and the oscillometric measurement. The Korotkoff microphone measurement uses a microphone to record heart noises. Thanks to this method, the device can also provide correct readings for patients with cardiac arrhythmias. Oscillometric measurement measures pulse waves and is used in most automatic blood pressure monitors. Comfort Air technology allows a more comfortable measurement on the upper arm. The measurement analysis can be easily carried out thanks to the traffic light system. The device can detect and display cardiac arrhythmias.
