Temperature Measurement Display: temperature thermometers use two sensors, one inside the device and the other extended to an external probe, which is waterproof. Both sensors can measure temperature simultaneously and display it on the software interface. Hyperbola Display: The real time temperature inside and outside is converted into a hyperbola, and the temperature monitoring is more clear and clear. Log Function: Real time temperature data can be recorded and automatically saved in related files. Warning Setting: Set the warning temperature and start the function.
