REH YK-81C vingertop-pulsmeter met OLED-display, SpO2- en polsfrequentiemonitor

With a SpO2 measurement range of 70% to 99% and accuracy of ±2%, the REH YK-81C delivers clinical-grade blood oxygen saturation readings in seconds. This compact fingertip pulse oximeter pairs a dual-color OLED screen with six display modes, ensuring clear visibility from any angle. Powered by two AAA batteries, it offers approximately 20 hours of continuous monitoring, making it a reliable companion for home health tracking or on-the-go spot checks.

Overview

The REH YK-81C is a fingertip pulse oximeter designed for adults and pediatric patients with finger thickness greater than 10mm. It non-invasively measures arterial oxygen saturation (SpO2) and pulse rate (PR), displaying results on a bright OLED panel. The device automatically shuts down after 8 seconds of inactivity to conserve battery life, and a low-voltage indicator alerts you when batteries need replacement. Its ABS plastic housing is durable yet lightweight, suitable for daily use.

What stands out

• Dual-color OLED display with adjustable brightness (4 levels) and plethysmograph waveform for signal quality assessment.
• Six display modes: four directional orientations and two data formats for flexible reading.
• Wide pulse rate range from 30 to 250 bpm with accuracy of ±2 bpm or ±2%, whichever is greater.
• CE and FDA certifications ensure compliance with medical device standards.
• Automatic power-off and low battery indicator enhance energy efficiency and user convenience.
