-Better accuracy - heart rate monitor and blue finger Pulse Oximeter good design
/ / Description \ \ easy to use, just insert a finger Pulse Oximeter and press the only button to activate the device. With a display of organic light emitting diode, showing the percentage of the value of SpO2 and pulse rate, the results are updated every second. The display brightness is also adjustable. Read oxygen saturation and pulse rate is always easy. Compact and lightweight, this Pulse Oximeter is portable! It shuts off automatically after 8 seconds if there are no finger. / / Content \ \ is supplied in a carton, without batteries (2 x 1.5 V AAA). / / Features \ \-SpO2 Monitor and show the waveform of pulse - low energy consumption in continuous operation during 50 hours - small, light and easy to carry - low voltage, automatic shut-off alarm - works with standard AAA batteries / / functions \ \ [SPO2] + range: 70% - 99% + accuracy: ± 2% of 70% - 99%, unspecified stage (<70%) for SPO2 + resolution: ± 1% + low perfusion : <0.4% [PR] + measurement: distance: 30bpm Precision +-240BPM: ± 1% or ± (largest) 1BPM + power supply: two AAA batteries + standard energy consumption below 30 mA + auto shut-off: product stops automatically without signal for 8 seconds + Dimension: 62 mm * 32 mm * 33 mm + operating temperature: 5 ° C - 40 ° C + storage temperature: - 10 ° C - 40 ° C + ambient humidity: 15% to 80% of the operation + 10% to 80% in storage + atmospheric pressure: 70 kPa, 106 kPa / / precautions \ \ avoid the use of a Pulse Oximeter in the presence of an excess of light (full sun or under intense light), as it can alter the infrared sensor and give erroneous results.
