LC72-DO Industrial Dissolved Oxygen Meter Product Name: LC72-DO Industrial Dissolved Oxygen Meter Model: LC72-DO Key Features of the LC72-DO Industrial Dissolved Oxygen Meter: 1. Automatic sensor cleaning function with configurable cleaning duration and intervals. 2. Simultaneous display of multiple parameters (temperature and mg/L on the same screen). 3. Online value calibration capability. 4. Manual/automatic temperature compensation: automatic compensation when connected to an external temperature probe; switches to manual mode when disconnected. 5. Alarm function: isolated alarm signal output, customizable upper and lower alarm limits with hysteresis cancellation. 6. Automatic self-check upon startup: verifies all parameters are within normal range and allows self-recovery or calibration if not. 7. Industrial watchdog timer: ensures the instrument does not freeze by automatically resetting in case of abnormal operation. 8. One-key restoration: allows non-specialized users to revert to factory settings in case of misoperation. Technical Parameters of the LC72-DO Industrial Dissolved Oxygen Meter: 1.
