The amount of dissolved oxygen in a water sample is measured using fluorescence technology in this portable, easy-to-use probe. Measuring at a range of 0-20.00mg/L or 0-200% saturation level, this probe is manufactured in strict accordance with the international standard of the ISO 9001: 2015 quality management system.
Green LED light irradiates a red fluorophore within the probe. The quenching properties of oxygen in the water sample reduce the lifetime of the red fluorophore, producing an inversely proportional relationship between dissolved oxygen content and red fluorescence, this can be measured to mg/L or percentage saturation level.
RFLSI Pro Laser Speckle Perfusion Imager is based on the latest LSCI technology (Laser Speckle Contrast Imaging/LSCI, Laser Speckle Ratio Analysis). With the advantages of the unique non-contact, high time and spatial resolution, rapid imaging, it provides a new recording way for the life sciences basic research and clinical medical, which can achieve real-time dynamic blood flow monitoring and video imaging, it is the vital basis for understanding the organization, organ pathology and physiological indicators. The instrument does not need any contrast agent, the time resolution can be in milliseconds, the spatial resolution can be in microns. It also achieves the requirements of real-time observation of microvascular blood flow distribution and relative changes in values.
