New Nano-Engineered Laboratory Based Optical Dissolved Oxygen System Launched

摘要

"Optical technology replaces the classic Galvanic method of dissolved oxygen measurement and offers many advantages." Aquaread Ltd is the UK's only designer and manufacturer of multiparameter water quality testing instruments. The company originally launched their GPS Aquameter in 2008 which measures up to 20 different parameters at once, including pH, dissolved oxygen, turbidity, conductivity and records GPS coordinates - an innovation in field measurement. Following the success of this instrument, Aquaread Ltd have launched a new electrode designed specifically for use in the laboratory, which measures dissolved oxygen using optical technology. Optical technology replaces the classic Galvanic method of dissolved oxygen measurement and offers many advantages. The Galvanic method features a delicate oxygen permeable membrane. During measurement oxygen must pass through the membrane and react with the electrolyte solution within the membrane cap. This creates a current proportional to the amount of oxygen present.
