LC-DO-3T Touchscreen Benchtop Dissolved Oxygen Meter, 0-200.0% Saturation (CAT#: STEM-BC-4006-ZJF)

The LC-DO-3T is a touchscreen benchtop instrument for high-precision dissolved oxygen and temperature measurement. It is designed for routine water analysis, educational laboratories, and scientific research. A 7-inch TFT color display with 1024 × 600 resolution provides responsive capacitive-touch operation. The internal microprocessor supports automatic calibration, data storage, function settings, and result export. A polarographic dissolved oxygen electrode with a built-in temperature sensor enables automatic temperature compensation. Manual salinity and atmospheric-pressure compensation support accurate testing under varied environmental conditions. Digital filtering and sliding-difference technology improve response speed and measurement reliability. The electrode polarizes within three to five minutes and uses a replaceable combined membrane cap. The system stores up to 2,000 results and supports USB transfer, Bluetooth printing, and compatible mobile application connectivity.
