Pulse Oximeter LY-02KT with 2 complementary Duracell Optimum batteries The Pulse Oximeter LY-02KT is a low-cost finger pulse oximeter designed for measuring blood oxygen saturation (SpO2) and pulse rate. While specific details about the LY-02KT are limited in the search results, insights can be drawn from related studies and descriptions of similar devices. Key Features and SpecificationsMeasurement Range: Typically, low-cost pulse oximeters like the LY-02KT measure SpO2 levels ranging from 70% to 99% with a resolution of 1%.Pulse Rate: They can also measure pulse rates, usually within a range of 30 to 250 beats per minute (BPM).Display: Many models feature a dual-color OLED display, which provides clear readings of both SpO2 and pulse rate.Battery Life: Devices in this category often have a long battery life, with some lasting over 30 hours of continuous use.Accuracy: Accuracy can vary; studies have shown that some low-cost pulse oximeters may not meet clinical standards, particularly at lower saturation levels (below 80%).
