Small digital pulse oximeter
Light and small finger pulse oximeter that clips onto the fingertip of the index finger and displays the number of pulses and the percentage of blood oxygen saturation as well as a pulse wave graph. Light, easy to use and low energy (30 mA, the two original AAA batteries will last 20-32 hours without interruption.) Automatic shutdown after 5 seconds of not being used and battery charge indicator. Screen mode can be changed. Includes: polyethylene bag, 2 x AAA batteries, strap and instruction manual.TECHNICAL INFORMATION11” OLED colour screen with 96 x 64 resolution. SpO2 measurement range: 0% to 100%. Pulse measurement range: 30 bpm to 250 bpm. Batteries: 2 x 1.2V AAA alkaline batteries with acceptable range of 2.6V to 3.6V. Energy consumption: less than 25 mA. Resolution: 1% for SpO2 and 1 bpm for pulse. Margin of error: SpO2: + 2% (+ 4% in cases of weak pulse). Heart rate: + 2 bpm or 2% (maximum). Optical sensor: red light (wave length is 660 nm, 6.65 mW). Infrared (wave length is 880 nm, 6.75 mW). Dimensions: 6.6 x 3.6 x 3.3 cm. 50 g (including batteries).
