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.
Made of high quality 100% pure virgin medical grade polypropylene so you won’t find recycled plastics in our tips. We pre-test the resin to ensure no extractables are present. Every lot is lab tested and certified free of detectable Nuclease (Rnase/Dnase), Endotoxin (pyrogen) contamination and certified to U.S.P. results. Resins are pre-tested for metal contamination. Tips are racked and packed in a teal rack. These racks are made of polypropylene and are autoclavable repeatedly. They have sturdy latch hinges that won’t come apart like lesser quality tip racks and a special snap lock designed so that it will not catch on your gloves.
