We can highlight some features of this finger pulse oximeter such as: Integrated sensor for measuring blood oxygen saturation (SpO2) and cardiac pulse. OLED colour display showing SpO2 and pulse values, with waveform and column graph. Features 6 display modes and 10 adjustable brightness levels. Compact and lightweight design. Easy to carry and use. Low power consumption. Automatic shut-off after 8 seconds. Low battery indicator. Includes: polyethylene bag, 2 AAA batteries, strap and instruction manual. *For an SpO2 level of 92% or lower, it is recommended to consult a specialist. Technical characteristics of the finger pulse oximeter: Display: OLED. 10 adjustable brightness levels SpO2 measurement range: 70 ~ 100% Pulse measurement range: 30 bpm ~ 250 bpm Power supply: Batteries: 2 x 1.5V AAA alkaline batteries 1.5V 1200mAh Power consumption: less than 40 mA Resolution: 1% for SpO2 and 1 bpm for pulse Error margin: ± 2 % in 70~100 % SpO2 measurements 30bpm~99bpm, ±2bpm; 100bpm~235bpm, ±2% Optical sensor: red light (wavelength is 660 nm, 6.65 mW). Infrared (wavelength is 880 nm, 6.75 mW) Dimensions and weight: 5.8 x 3.5 x 3.4 cm, 30 gr (without batteries). We like the digital pulse oximeter because of: Its OLED display: highly visible and with a good brightness setting. Its lightness: it takes up very little space and is easily transportable. Its low power consumption: with two AAA batteries you can use this product for a long time.Features ACCURACY: with the pulse oximeter you can determine the percentage of oxygen saturation of haemoglobin in the blood in an accurate, safe and non-invasive way COMPACT AND LIGHTWEIGHT DESIGN: due to its dimensions and weight (just 30 grams) it is ideal for carrying it with you wherever you need it LOW CONSUMPTION: it only requires two AAA batteries that consume less than 40 mA. In addition, it has a low battery indicator so that you are not caught unawares when it is completely disconnected SAVING MODE: it has an automatic shutdown system that is activated when the device is not used for more than 8 seconds.
