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.
Our Digital Refractometer is a high-precision optical instrument designed with the principle that different liquids have different refractive indices.
This novel apparatus is portable, easy to operate, fast detection, and with accurate results. Quickly detect sugar content in fruits, vegetables, freshly squeezed juices, beverages, food processing industries, and honey.
Our digitalrefractometer clears the uncertainty associated with conventional refractometers and it is portable, easy to clean and store.
