LC-DO-3S Keypad Benchtop Dissolved Oxygen Meter, 0-20.00 mg/L (CAT#: STEM-BC-4005-ZJF)

The LC-DO-3S is a keypad-operated benchtop meter for measuring dissolved oxygen and temperature in aqueous solutions. It is suitable for routine water analysis, education, scientific research, and laboratory testing. A 6.5-inch white-backlit LCD and long-life tactile keys provide clear display and reliable operation. The built-in microprocessor supports automatic calibration, data storage, parameter setting, and data export. A polarographic dissolved oxygen electrode with an integrated temperature sensor supports automatic temperature compensation. Manual salinity and atmospheric-pressure compensation improve measurement accuracy under different sample conditions. Digital filtering and sliding-difference processing enhance response speed and reading stability. The electrode requires only three to five minutes for polarization and uses a convenient combined membrane cap. Up to 2,000 result sets can be stored and transferred by USB, Bluetooth printer, or compatible mobile application.
