Body temperature is a significant indicator of health status. There are devices that allow you to measure temperature in a non-contact way. One of them is a digital infrared thermometer.
Device features
An IR thermometer is a device that can remotely measure the temperature of any surface. If handled correctly, it shows high accuracy. At home, the device is great for measuring the temperature of a sleeping baby, while not in contact with his body. In industry, a digital infrared thermometer is used to determine the temperature readings of objects that are in a hazardous environment or under voltage.
Varieties
They are classified by measurement method. There are ear thermometers that stand out with high accuracy, but require some skills from the user. When using them, the auricle should be pulled back. It is forbidden to use this device for inflammation of the middle ear, and also when the child is screaming.
There is a frontal device that gives evidence after it touches the skin in the frontal or temporal zone. There is a non-contact digital infrared thermometer that resembles a gun in shape.
Advantages and disadvantages
Ease of use is one of the advantages of these temperature meters. Other benefits include:
- absolute safety;
- ease of use;
- instant measurement;
- the ability to determine temperature over a wide range.
The readings on the infrared thermometer are displayed on a large display. By sound signals, the device reports the end of the measurement and an increase in temperature. The display has a backlight, so the result is visible at night.
These devices also have disadvantages, one of them is a high cost. It is also noted that such thermometers, unlike ordinary mercury, are less accurate. Therefore, it is recommended to use an average value. In addition, a large error in the readings is obtained when measuring a sweaty body or after taking a hot meal.
User's manual
The instructions describe in detail the algorithm of actions. In order to obtain toned data, it is impossible to drop, hit a digital infrared thermometer. Ensure that the batteries are charged. It is necessary to wipe the sensor and the liquid crystal display with a cloth moistened with alcohol.
Before measuring with a non-contact infrared thermometer, the skin must be wiped dry. To prevent the device from overheating during repeated measurements, after a fourth time, a 10-minute break must be taken. To determine the error, you need to measure the temperature with good health and compare it with the norm - 36.6 degrees. The deviation that will turn out can be used to clarify the result with further use.
GM550 with laser pointer
This digital infrared laser thermometer is designed for non-contact temperature measurement in the range from -50 to + 550 ° C. On the back there is a backlit display where the measured temperature is displayed. There are 3 buttons around it:
- turn on / off the backlight;
- switching the displayed temperature in degrees and fahrenheit;
- turning on and off the laser type designator.
This thermometer is made of durable plastic. The case has the shape of a gun, assembled efficiently, it is very convenient to hold it in your hand. The power button is the trigger. At the bottom of the handle there is a slope, thanks to which the pyrometer can stand horizontally and vertically.
DT-635 Digital Infrared
The Dt 635 Digital Infrared Thermometer is universal. They can measure body temperature in the ear, on the forehead, as well as air and fluid. The device can take readings in the range from 0 to 50 degrees. They appear after 1 second, the maximum error is approximately 0.1 degrees. The device has a memory, thanks to which you can view the results of recent measurements. In addition, it contains:
- room thermometer;
- clock;
- alarm, which by means of sound warns of high temperature.
Also in this thermometer provides automatic shutdown. The case is made of durable material that can withstand shock when dropped. He has no shortcomings. Convenient use allows you to get extremely accurate indicators.
CEM DT-8806S 482117 - high quality
This model of digital infrared thermometer can be used for non-contact temperature measurement:
- body;
- water;
- food;
- all kinds of surfaces.
It is distinguished by the presence of a body that is durable with respect to impacts, capable of withstanding a fall from a height of human growth. The device operates in Body mode from 32 to 43 degrees and Surface mode from 0 to 60 degrees. The user can set the sound signal to exceed a certain temperature limit. The device runs on 2 batteries. If the downtime lasts 7 seconds, then it will turn itself off. The LCD screen has a built-in backlight. The control panel with buttons is located on the side. In addition to these digital infrared thermometers, there are a number of other models.
