It's not easy to be a parent. Children's illness is the most painful thing for parents. In addition, children will have fever when they are sick. Most families have thermometers, especially for families with children. 38.5 ℃ is a critical point for children to have fever. Below this temperature, physical cooling is generally enough; But if it is higher than this figure, it is necessary to use some antipyretic drugs appropriately. So it is very important to monitor the child's temperature during illness. For young children, hyperthermia can cause convulsions. As a parent, the author has experienced it once. Bao Ma said she didn't want to have it again in her life... This shows the importance of thermometer for a family.

The author has two mercury thermometers at home, one is an old triangular thermometer, and the other is a new wide body thermometer that is easy to read. There is no doubt about the accuracy of the mercury thermometer, but the mercury thermometer has a long measurement time, which requires relatively quiet measurement conditions for children. Due to the incompatibility of children's measurement, the first choice is the infrared thermometer. The author also hesitated between the infrared electronic thermometer and the infrared ear temperature gun. In addition to brands such as Borang and Omron, there may be large measurement errors, but brands such as Omron are more expensive. The author finally bought a cheap domestic infrared electronic thermometer with the attitude of trying. Although the measurement is not so accurate, it is very convenient to measure the temperature trend of children with fever. In addition, due to the work needs of the author, there is also a thermal imaging infrared thermometer, but measuring the child's temperature is no reference. This time I would like to thank Lei Feng.com for the trial of the third generation ear temperature gun of Bangmi. In the following evaluation process, I will conduct a comparative evaluation of my existing equipment.

First, let's take a look at the packaging box of Bangmi. The packaging box is not as simple as other products. A picture of sleeping children measuring their body temperature with Bangmi thermometer is on the front, which seems to be cordial. The trial products are labeled with the logo of "computer trial".

The red eye-catching logo in the upper right corner is the logo of the iF German Design Award. The bar miller thermometer obtained In 2017, iF International Design Award became the only product in this category. The German iF International Design Award is famous for its award concept of "independence, preciseness and reliability". Winning the iF International Design Award means that the excellent design quality is recognized worldwide.

The back of the box.

It is easy to operate. Download APP, open Bluetooth, and bind the bar thermometer to use.

The model and parameters of the bar mil thermometer are marked on the side. The model is FT-F21, and the accuracy within the normal temperature measurement range is ± 0.2 ℃. The maximum allowable error required by the national standard for ear temperature gun is ± 0.2 ℃. The power supply is two No. 7 batteries, which communicate with mobile phones via Bluetooth.

After opening the packing box, there was a layer of protective box inside, and the logo of Bami came into view.

Finally, I saw the true face of the Bang Mille Thermometer.

In addition to the bar mil thermometer, there is a separate packaging box for the battery and instructions.

Accessories are as follows:

Rod Mille Thermometer (with probe protective sleeve) X1

No. 7 (AAA ）Battery X2

Instruction X1

The bar miller thermometer does not adopt charging design, but is powered by two No. 7 batteries, two of which are attached with the machine. Open the rear battery cover to install the battery.

Five holes were found unexpectedly in the battery compartment. There are test points inside. They should be reserved for calibration or upgrade procedures.

Battery compartment sticker

Instead of adopting the shape of traditional ear temperature gun, the bar miller thermometer is the original pebble shape with smooth and round surface and excellent appearance and grip. There is only one button on the front, which is simple and easy to operate. The temperature measurement part is a high-precision infrared thermopile sensor, which can measure quickly and accurately.

Under the smooth and round surface of the bar miller thermometer is hidden a dot matrix display screen composed of 80 bright LEDs, which is displayed in the specification of 5 * 16. When the LED is not lit, the two are fully integrated. When the man-machine display is simple and clear.

Click the button on the front of Bangmi to start the machine. After power on, the screen will scroll and enter the Bluetooth binding state. At this time, the 3 LEDs below the button will flash to remind you of breathing. It can be used even without Bluetooth binding. Press the button again to measure.

The measurement results can be displayed on the cobblestone smooth surface.

When the measured temperature is too low, LO low temperature warning will also be displayed. LO is displayed when the temperature is lower than 32 ℃, HI is displayed when the temperature is higher than 42.9 ℃. ERR will also be displayed when the ambient temperature of the product is exceeded.

Normal test result, 36.8 ℃. The measurement is accompanied by beeping.

When the temperature is normal, there will be a "smiling face" display after the display.

When there are multiple groups of measurement data, there will be a scroll prompt on the right side of the screen, Swipe the screen up and down in the direction prompted to view the five groups of historical body temperature data.

Now that we have learned how to operate, we should download APP for mobile phone operation. The measured data is uploaded to the mobile phone through Bluetooth to generate a data curve, which is convenient for monitoring the temperature change of the measurer at all times. The advantage of smart hardware is that mobile APP can provide Internet links and provide more solutions.

The QR code of Bangmi's instructions is not the direct download address of the APP, but the WeChat official account of Bangmi. You can download the APP after following the official account.

After entering the APP, you need to register and set the baby information.

The main interface of APP is divided into three parts: the results that can be measured realistically on the home page; The recording interface can record the baby's temperature, symptoms, medication and other information; The baby interface can record the baby's daily life.

The settings in the upper left corner can be used to set various contents.

The binding of the bar miller thermometer is also relatively simple. One thing is that the GPS must be turned on when Bluetooth is turned on.

The remote view function shared by family members is more practical.

The author has an infrared forehead temperature gun and an infrared imaging thermometer at home, but the accuracy of temperature measurement is better than that of mercury thermometer.

Next, I will conduct a simple comparative test between the rod miller thermometer and the following temperature measuring equipment.

FLIR's infrared imaging thermometer is not for medical use, but for industrial use, so the measurement of body temperature is not completely reliable.

The following figure shows the measurement of the author's baby. The measured forehead temperature is 37.5 ℃.

The measurement result of infrared temperature measuring gun is 36.5 ℃

Although the measurement of bar miller thermometer is not as good as that of infrared forehead thermometer, it is also very fast. Insert the temperature measuring head of the rod miller thermometer into the ear canal, and tap the button to display the temperature in about one second. To improve the accuracy of temperature measurement, gently pull back the ear of the measurer to make the ear canal straight.

The measurement result of rod miller thermometer is 36.8 ℃. The forehead temperature measured by the same infrared thermometer gun is 36.5 ℃, with a difference of 0.3 ℃.

After the measurement is completed, the data will be automatically synchronized to the mobile phone APP interface.

Because the baby didn't sleep, he didn't cooperate with the mercury thermometer. It can be measured only after the baby is asleep. The body temperature is about 37.05 ℃.

The measurement results of the rod miller thermometer are as follows:

Conclusion: From the above simple experimental comparison, it can be seen that the measurement results of the rod miller thermometer are satisfactory. The data given by mercury thermometer and ear thermometer will be different, but they are all within a reasonable range, because their main function is to detect the change of human body temperature, which may change every second. The bar mil thermometer is much faster than the ordinary mercury thermometer. It doesn't need to wait for more than a minute. It only needs a second to get the data, and there is no fear that glass products are easy to break. Although the infrared imaging thermometer can also measure temperature, it is not for medical use, but for industrial purposes, so the measurement of body temperature is not completely reliable. One last word: If the baby's temperature is found to be on the rise, parents should pay attention to it. The rod miller thermometer can measure quickly and accurately, which is worthy of parents' possession.
