PPG-2R-880 / PPG-2R-940 Reflectance SpO2 Module

PPG-2R-880 / PPG-2R-940 Reflectance SpO2 Module

The PPG-2R-880/PPG-2R-940 works with the AECG100 main console or SECG 5.0 AIO Multi Vital Sign Simulator, as the first reflectance SpO2 performance tester designed for R&D in manufacturers. This dual-channel optical module outputs R and IR analog signals to test blood oxygen saturation (SpO2) and heart rate functions. Besides, it also allows users to individually adjust the R/IR’s rate of change of respiratory signals in PPG and set up add-on noise. It’s suitable for the development and verification of reflectance PPG products such as wearable devices to test performance.
