Optical DO Meter

The  Portable Optical Dissolved Oxygen Meter - Single Parameter (DDOPRO10) is a rugged, handheld instrument designed for accurate, low-maintenance, on-site dissolved oxygen analysis. Utilizing optical/fluorescence sensor technology , it measures DO concentration (0.00~20.00 mg/L) and percent saturation (0.0~200.0%) with automatic compensation for temperature, barometric pressure, and manual salinity changes .

Featuring a 3.5-inch TFT color screen and a user-friendly UI interface , the Portable Optical Dissolved Oxygen Meter - Single Parameter (DDOPRO10) simplifies field water quality testing. It stores up to 3000 data sets, supporting GLP-compliant documentation, and its rechargeable lithium battery with a Type-C port ensures convenient power for mobile use. The system includes an optical DO probe (DODO01-3M) with a POM shell and stainless steel protection sleeve , a hard carrying case, and charging cable .

For the water quality specialist, the Portable Optical Dissolved Oxygen Meter - Single Parameter (DDOPRO10) is essential for monitoring dissolved oxygen in purified water systems (WFI, dialysis water), assessing aeration in wastewater treatment, and verifying water quality in pharmaceutical production and hospital facilities . Its optical technology eliminates the need for electrolyte refills, membrane cap replacements, long polarization times, and frequent calibrations — dramatically reducing maintenance compared to polarographic DO meters and allowing for precise measurements without sample stirring .

For the patient, this rigorous monitoring helps ensure that water used in dialysis and other medical treatments meets stringent safety standards, preventing potential harm from improperly treated water. The meter provides quick (<15 second response), reliable, and verifiable results for any application requiring critical DO measurement.
