The FINGERTIP PULSE OXIMETER LK87 is a pulse oximeter designed to measure the amount of oxygen in capillary blood. The device is equipped with an LED display, which provides low power consumption and, as a result, the ability to monitor the patient's condition for a long period of time. And the compact size, low weight and high accuracy of the results obtained allow this device to be used practically in any conditions. Indications for use: Chronic diseases of the cardiovascular system Respiratory system diseases When undergoing oxygen therapy Control of the level of loads during sports Basic properties: Built-in SpO2 sensor and touch display Small in volume, lightweight and easy to carry Product operation is simple, low power consumption Customizable menu functions SpO2 values on display Heart rate display and bar graph Waveform Impulse Representation Automatic shutdown function in case the device is not in the measurement state, it will automatically shutdown within 5 seconds or if a finger falls out of the probe during measurement Specifications: SpO2 Measurement range: 0% ~ 100%, (1% resolution). Accuracy: 70% ~ 100%: ± 2%, below 70% undefined. PR Measuring range: 30bpm ~ 250bpm, (1bpm resolution) Accuracy: ± 2bpm or ± 2% (choose more) Power consumption: less than 25mA Power: 1.5V rechargeable lithium battery × 2 Performance measurement in a weakly filled state: SpO2 and pulse rate can be displayed correctly when the pulse-ratio is 0.4%. SpO2 error is ± 4%, pulse error rate is ± 2 bpm or ± 2% (select more).
