Laser Thermometers uses , advantages and disadvantages
They work on the principle of laser , When any substance is hot , it radiates this heat from all of its parts , So , the molecules in this area will vibrate with greater velocity , Laser can measure this increase in velocity , It is converted into the temperature reading which the laser thermometer provides .
Thermometer technology has improved vastly in the recent times , Laser Thermometer works on the laser principle , Laser Thermometer shape is more or less like a gun and there’s a region from where the laser is emitted , The laser-based thermometers are called as non-touch thermometers .
Since any hot body will emit the equal amount of the heat radiation from all of its parts , Laser thermometers can be pointed at any point on the surface of the body , The reading is almost similar , irrespective of where this actual point is located .
Laser thermometers advantages
They don’t really need to be brought in contact with the object whose temperature needs to be measured , Laser thermometers can measure temperature from a remote location and it is only necessary that the path of the laser shouldn’t be obstructed .
The results are instantaneous , It is a great benefit , especially when creating the clinical thermometers for the infants , By using the thermometers which work on the laser principle , it is no longer necessary to place the thermometer on the patient’s body and wait for a minute before taking the reading .
All these thermometers are digital that makes it much easier to get readings from them , Laser technology thermometers work on the simple physics concept where the molecules of matter are constantly in the motion to generate the temperature which is recorded using the laser thermometers .
The laser thermometer using infrared feature could convert the infrared energy of the targeted object into the electrical signals be fore displaying them into the temperature units .
There is no physical contact on the target with the laser thermometer held at a distance , The digital display of the object’s temperature is viewed on the LED panel in either Celsius or Fahrenheit .
The laser technology is applied in infrared thermometers as applied widely in the clinics and the hospitals , The laser thermometers are used to capture the patients’ temperature without any form of physical contact for greater degree of safety especially with contagious diseases .
They are used in measuring the temperature in the foods to be served , The food can be either hot or cold to determine its temperature , They are known as the cooking thermometers , The infrared cooking thermometer is used by chefs who are picky about the right temperature of their foods before serving to their patrons .
The laser thermometers are used in various industries on the heat leakages , They are very useful devices to ensure the safety at the work place in high danger manufacturing environments during the production at various phases , They can warn supervisors of impending dangers when the heavily operated machineries are heated up too much before a meltdown or breakdown .
The laser digital thermometer is known as non-contact laser thermometer because it can give the precise reading without coming in contact with object or subject , You have to make sure that the path of the thermometer and the substance whose temperature is to be taken is obstacle free .
You need not point the thermometer at a certain place of the substance , The non contact thermometer records the precise reading of the object by way of radiations given out by the object and there are a wide variety of laser thermometers are available in the market .
When you travel most of the time then infrared thermometer with laser is best for you , The laser digital thermometer is used for measuring the temperature of the infants and various medical purposes and it can help the fire fighters about the potential burning stage .
The Laser thermometer is very beneficial for the electrical or mechanical professionals also , They can used to locate the hot area on the electric circuit board or on the mechanical equipment .
The laser thermometers found to be the best measuring tool for the researchers and scientists as they help to carry out certain scientific experiments , They can be used in the industries to determine the heat leakages and the routine laser thermometer scan can assure the safety of the place.
Laser thermometers are used in measuring the body temperatures , especially in the form of the ear thermometers that are extensively used for measuring the body temperature in babies .
Laser thermometers disadvantages
The light sensitivity is the only disadvantage of the laser thermometers , However , they may be handled in case we take some cautions during the time of taking the temp belonging to the substance .
The true or accurate temperature could be secured if the laser thermometer is directed at the right object without any obstruction only , It can procure inaccurate or wrong temperature readings easily if the laser thermometer is not aptly handled .
Laser thermometers work basically using the laser principle , A hot or cold substance emits a certain amount of heat , The wrong radiation emission can be picked up and disastrous results can happen especially with lives are involved .
There is another disadvantage of laser thermometers which is the influence of its surroundings , The hot object emits the heat radiation that could be picked up by the laser thermometer , So , The temperature readings could be inaccurate if there are many objects around the target object .
Some proper training should be advocated to ensure the proper application for the accurate and safe implementation , The laser is emitted from the particular region for the accurate temperature reading , So , the laser ray must be accurately aimed at the right targeted surface for measurement .
The laser ray path can not be viewed except for the red dot on the surface of the objected pointed at , Unsteady hands could misguide the red dot with inaccurate temperature readings .
