The DT-635 infrared thermometer is a multifunctional device that provides you with the most accurate information in various areas of home life: the device is designed to measure body temperature (in the ear and on the forehead), indoor air, as well as contactless determination of the level of heating of food and other objects . Instantly obtaining the result “with one touch” is especially important when carrying out the procedure with a baby, as it does not give the slightest cause for concern caused by personal discomfort, and for round-the-clock monitoring of the room temperature, just set the “Clock + Room Thermometer” mode and your DT-635 will turn into in stylish and practical watches. The ability to replace the battery guarantees proper and long-lasting service of the device.
I read horror stories about wasting money on an infrared thermometer and was unsure whether it was worth buying. But what decided everything was that the most active opponents were fans of mercury thermometers, which characterizes.
My result after purchasing and testing: simply an excellent device!I decided to write this review for one simple reason: people, stop using mercury thermometers!
than the time you spent learning a new device. Unfortunately, I have to admit that the majority of negative reviews of infrared thermometers stem from the inability to use them and from a lack of understanding of the principle of their operation.
Drop your prejudices. One broken mercury thermometer is a much bigger problem for you and the environment,So, what do I want to say about this IR thermometer?
The spread of values in a series of measurements is very small, 0.1-0.2 degrees.
Measures instantly. Overall, very cool.One of the few disadvantages: the instructions were written by an amateur, “what I see, I sing about,” “the main thing is that it is beautifully designed.” The instructions are unstructured; measuring water temperature is generally written in the description in the watch/home thermometer mode. One important mode is not described at all in the instructions.
My usage notes:
When the thermometer is turned off, a short press turns on the mode for measuring body temperature (the “face” icon on the display), a long press on the thermometer that is turned off, apparently, turns on the measurement of the ambient temperature (the house icon).
The human body and surrounding objects have different emissivity, so do not confuse the modes!
There is no description of this moment in the instructions at all. And this is very bad, because... measurements are carried out by long pressing AFTER turning on, and you can completely accidentally turn on the thermometer with such a long press as usual, “out of habit,” and not notice that it turned on in a different mode.And if you turn on the thermometer with a long press (i.e., turn on the environment measurement mode), and measure body temperature, then the body temperature readings will be underestimated by about 2C!
To switch from ambient temperature measurement mode to body temperature measurement mode, you need to wait automatic shutdown thermometer and turn it on with a short press.Also remember that surrounding objects, even of the same temperature, also emit differently (depending on the material), and the table for converting radiation power into degrees for all surrounding objects in the thermometer is the same, so the ability to measure the temperature of surrounding objects with this thermometer is very conditional.
It is also not very clear why you should run a thermometer over your forehead while measuring body temperature (as it is written in the instructions). While moving the thermometer, it is impossible to establish close contact with the skin, therefore, with this method of measurement, the thermometer is lying.
Measure at one point! Yes, the temperature at different points of the body can be different, especially, for example, if it rises. If in doubt, measure the temperature at several points sequentially. Installed at one point - pressed the button - released - took the result.
Installed at another point - pressed - released - took the result. And so on. Instead of one second, spend five, not a big problem. Or you can measure the ear temperature, which a thermometer can also do.Discrepancies between forehead temperature measurements and ear temperature measurements at normal temperature there is no body. I think the only reason to measure the temperature in the ear is to monitor the readings when rapid change body temperature (chills/fever), because Changes in skin temperature usually occur unevenly.
Because The thermometer sensor is non-contact, treat it like a camera lens. The principle is the same as that of a camera: registration of radiation, only the wavelength of the radiation is different (well, there are fewer “pixels”, only one:). Therefore: do not get dirty, do not scratch, do not get wet; if it gets dirty, wipe it carefully, without leaving scratches. All.
Also note that there is no protection for the sensor input window on the cap. The “window” may become dirty and scratched. I strongly recommend storing the thermometer in a case.
Enjoy using it! Let your thermometer never lie and always show 36.6!;)

It appeared not so long ago, but it managed to gain great popularity. Using it, you can measure the body temperature of adults and children with maximum accuracy. The process proceeds easily, without the unpleasant sensations that contact-type devices cause. Non-contact ones allow you to measure not only the temperature of the human body, but also water, air and other surfaces. But in order to use this type of device correctly, you need to know how to calibrate an infrared thermometer without errors.

But before purchasing, you should carefully consider the features of these devices, their functions and main characteristics.
Electronic infrared thermometer AND DT-635 was purchased by me at a pharmacy for 1,400 rubles with only one purpose: to measure the body temperature of a sick baby. The fact is that my youngest son is categorically against thermometers inserted into the armpits. In order not to traumatize the child’s psyche, I decided to take a thermometer that works quickly, “without noise and dust.”
I was looking for a contactless device, but in my town I found only an electronic infrared thermometer. This is what we will talk about in this review. Looking ahead a little, I want to say right away: this device has both advantages and disadvantages, but first things first.
About the configuration. The thermometer comes with a clear blue case,
with user manual, printed on good coated paper,
power supply (button battery),
All this equipment is in a cardboard box. There is also a warranty card here. By the way, it was never useful to me, because the thermometer worked properly, without breakdowns or complaints.
About methods of use. In general, this device can be called multifunctional, since in addition to measuring body temperature (in two ways), the thermometer can be used as a clock, a room thermometer, or a temperature meter for any objects. True, when we pointed the thermometer at the room heating radiators (in winter), it showed us “Error”. The fact is that the temperature of the measurement objects must be in the range from 0⁰ C to 50⁰ C. That is why the error appeared on the display.
There are two modes for measuring body temperature:
1. Temperature measurement in the ear.
How to do it? You need to remove the light blue cap from the device and wipe the thermometer sensor with medical alcohol.
Press the power button, after which all available symbols are first displayed on the screen, and then the “ear” icon and degrees Celsius remain. Insert the sensor into the ear canal and press the power button on the housing again. After the beep, you can look at the display.
2. Temperature measurement on the forehead.
In this case, there is no need to remove the cap.
First, press the power button of the device to check its functionality. The entire set of symbols appears and a double beep sounds. After this, press the thermometer to your clean forehead. By pressing and holding the power button, we move the sensor across the forehead slowly, not allowing the thermometer to move away, otherwise the data will be distorted. We release the button, hear a single beep and look at the screen.
The thermometer turns off in automatic mode. The explanation of the symbols is indicated in the thermometer’s operating instructions (see above).
About the advantages of the device.
- Fast measurement. It takes me a few seconds to run a thermometer across my forehead and find out the result.
- The child likes the device. Our torment ended with crying and screaming.
- Does not contain mercury. You will laugh, but before purchasing this thermometer, we used mercury thermometers. I always imagined with horror pictures of a broken thermometer and balls of mercury rolling around the apartment.
- Accuracy with minimal error. I emphasize that you need to take measurements RIGHT . To do this, I advise you to study the user manual.
About the shortcomings of the device.
- It is not very convenient to run a thermometer across your forehead, pressing the sensor tightly. The frontal bone is felt here, and the thermometer strives to “jump” from the forehead. It would be more convenient to take measurements on a softer place.
- The accuracy of the results decreases if the measurement is incorrect and the battery charge level is low.
Decide for yourself whether or not to buy such a thermometer. I don't regret this purchase.
