• Outstanding Performance: The Berrcom oximeter utilizes photoelectric detection principles to accurately capture blood oxygen signals, resulting in +/- 2% measurement accuracy. If the measured blood oxygen saturation falls below 94% or the pulse rate exceeds 130bpm or falls below 50bpm, the device provides an audible alarm and flashing measured value display to ensure timely attention to the measurement outcome.
• Hardware Upgrade: The pulse oximeter employs advanced algorithms and a sophisticated chip, delivering precise SpO2 (oxygen saturation level) and pulse readings in just 8 seconds. The results are displayed on a large LED display, providing you with convenient monitoring. Silicone shading design prevents external light and shadows from affecting measurements.
• Easy Operation: The finger clip pulse oximeter features one-button measurement, and the measurement results are displayed on a large digital LED screen that can be viewed from both directions. You can change the display orientation with each press of the oximeter button. It automatically powers off after 30 seconds of removing your finger to save energy.
