Please select the variation based on your needs; The Finger Pulse Oximeter measures the oxygen saturation levels, pulse frequency and the APG index (Acceleration Plethysmogramm). Therefore, it can quickly and simply determine the Arteriosclerosis status in relation to the SpO2 level. The Rossmax APG Index measurement, by which its reliability has been confirmed through a study at the National Taiwan University Hospital, allows for an assessment of the elasticity of the arterial walls through determination of the blood flow rate.Product Details SB 200 - Finger Pulse Oximeter SB200 - For determination of oxygen saturation and pulse frequency in adults and children - APG Index display with graphics - Arteriosclerosis status in 6 stages (tested through a study by the National Taiwan University Hospital) - Intuitive 1 button service - OLED display - Low weight and compact dimensions make it ideal for mobile use - With battery life display - Batterie operated with 2 AAA alkali batteries - Up to 16 hours service life with a single set of batteries - Automatic switchoff after approx. 8 seconds of non-use - Interchangeable display modes via quick touches of on/off button - Acoustic and visual alarm when limit is exceeded - 1 year manufacturer warranty - Dimensions: 63.5 x 34 x 35mm - Weight: 37g (without batteries) - Measurement range of SpO2: 35 – 99% - Measurement range of pulse frequency: 30 – 250 Bpm SB100 %Spo2 & Pulse Rate - Big LED screen display for easy reading Shielded Design blocks Ambient Light Biocompatibility & Anti-Allergic Design One-touch ON/OFF key Pulse Strength Indicator Cord attached - Economical & portable health management tool Ideal for oxygen therapy assessment Ideal for sleep apnea screening Ideal for health management Ideal for spot-check & continuous monitoring SB210 Artery Check Technology (ACT) embedded Bluetooth® Transmission Instant readings of SpO2, pulse rate and artery condition in 1 minute Shielded Design blocks Ambient Light Biocompatibility & Anti-Allergic Design Pulse Strength Indicator Two way, two color OLED display Cord attached
