Product Name: LC72-DO Industrial Dissolved Oxygen Meter

Product Model: LC72-DO

Key Features of LC72-DO Industrial Dissolved Oxygen Meter:

①、 Automatic sensor cleaning function allows setting of cleaning time and interval for the probe;

②、 Multiple parameters displayed simultaneously (temperature and mg/L displayed on the same screen);

③、 Online value correction function;

④、 Manual/Automatic temperature compensation: When an external automatic temperature sensing element is connected, the meter automatically compensates; if not connected, it switches to manual mode;

⑤、 Automatic alarm function: Isolated alarm signal output, with adjustable upper and lower alarm limits and alarm hysteresis cancellation;

⑥、 Automatic startup detection: Each time the meter is turned on, it automatically checks whether all parameters are within the normal range; if not, it can self-recover or be corrected;

⑦、 Industrial watchdog timer: Ensures the meter does not freeze; designed with a built-in watchdog timer that automatically resets the meter in case of abnormality;

⑧、 One-key recovery function (If non-professional operators perform incorrect operations, the meter can be restored to factory settings using the recovery key);
