Regarding the error of the thermometer: After all, it is a household thermometer, and it cannot be compared in precision with the professional thermometers that can easily cost hundreds or thousands of yuan. Please consider carefully before making a purchase.

After feedback from guests and our own comparison, we have found that the electronic temperature and humidity meter is more accurate than the mechanical one in terms of precision.

Temperature/Humidity and Health Knowledge

According to the research of physiologists, high indoor temperatures can affect the human body's temperature regulation function, causing body temperature to rise, vasodilation, rapid pulse, and accelerated heart rate. In winter, if the indoor temperature is often maintained at 25℃ or above, people will feel tired, dizzy, lethargic, slow thinking, and poor memory. At the same time, due to the large temperature difference between indoor and outdoor, the body finds it difficult to adapt, and is prone to catch a cold. If the indoor temperature is too low, the pulse and breathing slow down, subcutaneous blood vessels contract, the skin becomes overly tense, and the resistance of the respiratory tract mucosa weakens, which is easy to induce respiratory diseases. Therefore, scientists have determined the lower limit temperature for "cold tolerance" and the upper limit temperature for "heat tolerance" to be 11℃ and 32℃. While paying attention to the indoor temperature regulation, it is also necessary to pay attention to the indoor humidity. In summer, when the indoor humidity is too high, it will inhibit body heat dissipation, making people feel very hot and irritable. In winter, when the indoor humidity is high, it will accelerate heat conduction, making people feel cold and depressed. When the indoor humidity is too low, due to the large loss of water in the upper respiratory tract mucosa, people will feel dry mouth, dry tongue, even sore throat, hoarse voice and nasal bleeding, and are prone to catch a cold. Therefore, experts believe that the upper limit value of relative humidity should not exceed 80.The lower limit should not be lower than 30.
