Infrared thermometers can measure the temperature of any object remotely. The device reacts to heat radiation. The second name of the device is a pyrometer (from the Greek "fire" and "measure"). The principle of operation is based on capturing electromagnetic waves in the infrared range. After measuring their length, the signal is transmitted to a detector, which converts the received data into a digital value. The models presented on the Aliexpress website are usually equipped with a laser. Its beam serves only to indicate the target, but not for temperature measurements.
Infrared thermometers are larger in size than the usual mercury or alcohol models, popularly called thermometers. They resemble pistols with an LCD screen. The equipment measures temperature non-contact, but there are varieties that require short-term contact with the body.
In order to choose the best IR thermometer, you need to consider the following data:
- range of investigated temperatures - when working in a narrow range, it makes no sense to buy expensive models;
- working distance (sighting ratio DS) - DS 12: 1 means that the working distance of the model is up to 5 meters, DS 20: 1 - about 10 meters;
- emissivity - means the ability of the device to read the amount of reflected heat (there are models with adjustable and fixed coefficient), by default it is 0.95 (suitable for most materials);
- type of laser - for budget models it has one point and shows only the center of measurement, two lasers more accurately demonstrate the area of measurement;
- way of reflecting the information received - simple models are equipped with an LCD screen, more complex ones can be connected to a computer.
The top 15 features the best models for household and industrial use, as well as medical thermometers.
The best infrared thermometers for household use with Aliexpress
In everyday life, non-contact IR thermometers are used to detect heat leakage, study the thermal insulation of pipes and the tightness of windows. They are needed during repair work, in the kitchen during cooking, when diagnosing the condition of the car. Often, such equipment has additional functions: backlight, built-in memory, holding indicators on the screen. The most inexpensive Chinese models can only measure temperature. However, they are characterized by good accuracy. Therefore, the category includes both budget infrared thermometers and products in the middle price category.

Ability to create your own tables of correction factors
Price on Aliexpress: from 1 707.72 rubles.
Rating (2019): 4.7
The capabilities of this pyrometer are much wider than the functionality of budget household infrared thermometers. It allows you to contactlessly measure the temperature of objects, as well as the calculated dew point temperature, readings of air humidity. But its main advantage is the ability to create your own tables of radiation correction factors, without which it is impossible to ensure the accuracy of measurements. After all, the ability to radiate is different for each material, and the sensor of the device cannot know what exactly is in front of it.
Usually users are content with ready-made tables, but they are very approximate. By creating your own correction factors, you can make accurate non-contact temperature measurements. There is also an ultraviolet flashlight here. So you can check the authenticity of the bills. Customer reviews speak about the reliability of the device. They believe that this pyrometer from Aliexpress sets a new standard in infrared measurements.

We have this thermometer with a frog
As for the complete set, it contains: a guarantee, instructions, a cap for a thermometer sensor and a toy.
We bought such a thermometer for a child, but she did not want to keep a green thing with eyes under her arm and cried constantly. Therefore, there is no difference between a mercury and this thermometer in this regard.
The instructions tell you how to use the device and everything is simple there.
The only difference and advantage of this thermometer is safety. The part that needs to be placed under the armpit consists of an elastic material that the child cannot break.
This is where the pluses end, the minuses begin.
Before writing a review, I decided to check on myself how it works. And she was very upset. I know that now I definitely can't have a temperature, but the thermometer showed me 37 degrees. I know perfectly well the state when the temperature is 37 and now I could not have it.
It is especially offensive that the thermometer was bought for a child, and if you use the name when the child is sick, and he will show the wrong temperature, then there is no sense from him at all! When a child is sick, you don't want to dance with a tambourine near the thermometer so that it gives out the real temperature.
Well, the packaging says Japan, but in fact, China.
Considering the price of 350 rubles, it should also warn about a flu epidemic 😉
