Uh, warm gun, tell me.

Because of COVID-19's reasons, forehead temperature gun and thermometer have become indispensable daily necessities. Many people will doubt whether the forehead gun is accurate when using it. Under normal circumstances, electronic temperature measuring gun is still relatively accurate, but the premise is that the production quality of electronic temperature measuring gun must pass. Before buying, you can look for the brand of electronic temperature measuring gun with good quality and good reputation online. As the saying goes, you get what you pay. Don't be greedy when buying. Try to buy in large shopping malls. When using an electronic thermometer, you should read the instructions carefully and measure according to the instructions to avoid inaccurate temperature measurement.

What happened to the temperature gun? 1, the measured distance is wrong. Please pay attention to the instruction manual when using. If the instruction manual indicates that the measured distance is 1 cm, but the distance is 2 cm when you measure it, then the measured data will definitely be biased. In addition, when measuring, the hair on the forehead should be separated and measured when the sweat is dry.

2. The ambient temperature will also affect the measurement data. Basically, the temperature guns produced regularly will be marked, and the ambient temperature during use should be between 16-30 degrees. If the temperature measured at that time is too low or too high, it will affect the measurement data in temperature measuring gun.

3. Hold the warm gun on your forehead accurately. The front of the forehead temperature gun is a temperature sensor, which needs to receive radiant heat. If there is a deviation in the position during measurement, the temperature sensor cannot completely measure the forehead position, which will lead to inaccurate measurement results. So when using it, let the gun head face the forehead, just like people say that shooting is the same posture.

4. Don't take your temperature after strenuous exercise or taking a hot bath. Because both exercise and hot water can lead to a short-term increase in human body temperature, the measured temperature is relatively high at this time. On the other hand, if the human body is outdoors at low temperature, or when washing cold noodles or taking a cold bath, the measured data will also drop.

Electronic temperature measuring gun is being widely used. Compared with mercury thermometers, electronic temperature measuring gun is safer to use, especially in families with children. Because the mercury thermometer is fragile, once it is broken, the mercury inside will immediately become beads and be scattered everywhere. If the cleaning is not timely or thorough, it is prone to dangerous situations such as eating by mistake. At present, many countries in the world have banned the use of mercury thermometers; At the same time, compared with mercury thermometer, electronic temperature measuring gun can measure human body temperature quickly, and electronic thermometer can measure real-time human body temperature in just a few seconds. Reading is also convenient, easy to remember and helpful.
