Precautions 1. The heating part must be completely immersed in water and cannot be exposed to the water surface. 2. The heating part cannot be buried in sand and stones, otherwise it will cause circuit abnormality and fail to sense the water temperature. 3. Do not place a magnetic brush near the heating body to prevent the heating plate of the heating part from being magnetically damaged. Keep at least 20CM away from the magnetic brush. 4. Try to place the thermometer far away from the heating part and check the water temperature regularly. Note: Thermometers from different manufacturers will have some errors, and errors will also occur in different waters. Digital thermometers will have errors when the power is insufficient or used up.
