Ring details

Attention：

1.Make sure your surrounding temperature is not too hot or too cold.

2.Do not wear it when shower or swimming.

3.The digital only shows the temperature around finger It’s not a professional therrnorrneter.

4.If you feel ill,please use professional thermometer and take correct medical care !

5. if the skin temperature is lower than 27°C the digit will not appear
on the ring，make sure your finger is warm up to normal condition.
When you wear a ring on your finger for 20-30 seconds, it automatically displays the ceramic with temperature.

In winter, the temperature is low, and the ring is made of stainless steel. The heat transfer is slow, and the number may be displayed very slowly. You can immerse it in hot water to quickly display the number.Regarding the actual temperature: I have 28 degrees, although the body temperature is 36,6 and this is natural! T. K. The design of the ring uses a standard thermal tape of thermal releases, without any calibration and amendments to the fact that the ring on the inside is heated by the surface of the skin of the finger (which is already below the body temperature) and outside-dissipates the temperature into the environment. So the ring is not an active wearable real-time thermometer, but a keychain is a thermometer that needs to be immersed in the measured environment.
