- What does the temperature gun do?
Regarded as infrared or no-contact thermometers, the thermal guns along with other similar infrared gadgets are essentially temperature monitoring devices, designed to monitor body temperature from a short distance. The purpose of these devices is to measure your body temperature from a bit of a distance when using an oral/rectal thermometer would not be feasible, appropriate, and potentially harmful in the current COVID-19 scenario.
2. How does the tempreature gun works?
The temperature gun usually uses a lens to focus infrared light from a device onto a detector called a thermopile. The thermopile takes in the infrared radiation and turns it into heat. The electricity is sent to a detector, which uses it to ascertain the temperature of whatever the thermometer gun is pointed at. The temperature gun uses the infrared technology that allows it to scan and measure the temperature of the temporal artery on the forehead for quick and accurate measurements without touching the skin. It can memorize the last measurements and it has an audible alarm if the temperature is higher than 100.4℉.
3. How the temperature gun must be used?
There are certain instructions to be followed while using a thermometer gun. The device must be used at a proper distance. It should not be too close or too far away from the body in order to get an accurate reading. You need to position the thermometer gun carefully. It is advised to use it within the range of 1.2”-2” or as recommended by the manufacturer otherwise, the readings will not be accurate. The thermometer guns merely quantify the surface temperature of the skin which may fluctuate for many reasons. However, the temperature gun doesn’t measure the internal body temperature.
4. Is the temperature gun accurate?
Some people still doubt the accuracy of temperature gun. However, experts believe that if used correctly, thermometer guns are just as reliable as oral or rectal thermometers. No-contact thermometers are widely used for kids to get a temperature read. Similarly, it is also used in mass temperature screenings.
5. Why the use of thermometer gun has increased?
Increasing use of thermometer guns and such devices can be observed while entering the educational institutes, academies schools, colleges, cafes, airports, banks, hotels and offices in the aftermath of ongoing COVID-19 coronavirus outbreak for its special features and merits. The device can measure your surface temperature without a touch, hence eliminating contamination risk, at least in theory.
6. What are the main advantages of the temperature gun?
Convenience, user-friendliness, speed are few of the merits these thermal detection devices always have. Probably this is the only available way to screen large numbers of people in a short amount of time, otherwise seems to be probably impossible. Hence, the thermal scanners, temperature guns, and the like are as good as anything. The thermometer gun can read an individual’s temperature in mere moments, so there is no need to make a fussy toddler sit still for a minute or two. It is indeed the best way to help identify some people who should receive further investigation like taking proper history and undertaking physical screening. If used properly, it may potentially, perhaps help identify people who are feverish and merits a closer examination. So there are numerous reasons which provide sound justification to switch over from the old mercury thermometers of the past to latest digital forehead thermometers.
7. What are the key disadvantages of the temperature gun?
The two major problems with these devices are that you can’t always decipher what you are seeing or discern what you are feeling. The critics questioning accuracy of temperature gun argue that it is not profoundly clear how well these devices have been tested in laboratories for accuracy precision and reliability. Probably this is not the sole complication. In the current pandemic, there are certainly other things to take into consideration as the thermal screening can skip people who are infected with COVID-19 and may detect people who aren’t infected, in the first place. With faulty technology, problematic shape and doubts about the accuracy of temperature gun, it is said that the device tends to register lower temperatures. Hence, there is a genuine need for humanizing medical devices, a way towards better adherence and patient health care.
8. What important precautions to follow while using the temperature gun?
In the face, of scathing criticism, the accuracy of temperature gun may hinge on how they are used such as how far the device is from you, where exactly the device is aimed at, and how long and steadily it is held until the reading registers. If these precautions are not followed, you can imagine how many people might not be using a thermometer gun or other thermal reading devices properly. The bottom line is that how do you use a temperature gun actually defines how accurate it is.
9. Where can you buy the best temperature gun?
If you are searching for the best temperature gun by surfing through the reviews, you will be developing the feeling that most of the options available on the market space are equally good. Nevertheless, if you are aware of what to look for in the top-quality temperature gun then nothing like that. You will definitely understand all the essential features, a good thermometer must have. This post has figured out the most important things to be taken into account when looking for such a device.
10. What are the important factors to consider while buying a top-quality temperature measuring device?
While buying a superior temperature measuring device, there are a number of factors which must be taken into account. These mainly include but not limited to the following:
- Ease of use
- Kids friendliness
- Mass usage
Each of these factors has it own relevance and significance which are explained here.
Accuracy is the most vital of all the signs that make a subtle distinction among a top-quality, an average and a poor gun thermometer. The best way to know that your thermometer is accurate and reliable is to ascertain whether it has been clinically approved or not. While products’ quality, accuracy and safety are guaranteed by the manufacturers, it is best to opt for a top-quality temperature gun that has the approval of a specialized institution or approving body.
ii. Ease of use
Besides being accurate, a top-quality temperature gun should also be simple and user friendly when it comes to usage. A simple design, easy to carry and easy to operate can earn mass acceptability and popularity very easily as it guarantees more than just one way of using the device. Another benchmark of the device user-friendliness is to ascertain whether it can offer both Fahrenheit and Celsius readings which is in fact is a great sign of the manufacturer’ interest to pay attention to minute details.
As some types of thermometer has the issue of speed and management while measuring temperature of kids the types of temperature gun are considered best for home use because the dedicated probes offer a better and more accurate reading in less time.
iv. Kids friendliness
As children tend to be irritated with the use of certain oral and rectal thermometers, especially when they feel sick, a good temperature gun is highly recommended for the temperature readings being fast and reliable. A forehead thermometer makes it a lot easier to take the temperature of a child, especially in a situation when they are sick. Most of the non-contact thermometer guns give a safe and accurate read within no time. Since kids tend to be unwilling to wait for two minutes with a thermometer in their mouth or rectum will most probably stay still for a good temperature to measure their temperature.
Cost is an important factor for many of us while buying the best non-contact thermometer guns. But since a vast array of non-contact thermometers with different types, sizes and costs are available in the marketspace so the users have virtually no problem in selecting a best and affordable thermometer guns.
vi. Mass usage
Besides simplicity, ease of use, speed and affordability, mass usage is another alluring feature, the only available way to screen large numbers of people in a short span of of time, otherwise seems to be probably impossible. Hence, the market for digital thermometers, thermal scanners, temperature guns has been growing in an unprecedented manner in the wake of current corona pandemic.
