Quality infrared thermometers are highly useful to consumers in the domestic and industrial sectors requiring reliable temperature measuring devices. However, the selection process could prove to be a daunting task with the high imitations in the market that deceive unsuspecting consumers. Hence, it is necessary to be well-informed on the best characteristics of the infrared thermometer when selecting a quality unit for specific uses.
Types and Models Infrared Thermometer
There are many types of infrared thermometers in the market today as the demand increases with applications and benefits. These temperature gauging instruments are deemed to be highly sensitive to be most accurate in any type of environment or objects targeted.
More and more domestic consumers are deploying infrared thermometer in their homes while private and professional users are growing in numbers to assist them in enhancing their work productivity. Commercial as well as industrial sectors are active users with infrared thermometers to improve production outcomes that offer a higher tenacity on their goods and wares.
The wide array of infrared thermometer models offers a delightful choice in various shapes, sizes and designs as well as functionality and user friendliness. These non-contact thermometers are popular solutions that could fit the budget and requirements from the wide range of available choices in the market.
The more popular choice of infrared thermometer today is the gun or pistol shape IR thermometer which is easy to grasp for a sure hold and apt handling of the device in measuring temperature. However, the different sizes may prove challenging to different hands which may not be able to control the measuring device aptly for an accurate reading.
1) Brightness Sensor
A good IR thermometer should have a dynamic or strong brightness sensor which is highly sophisticated in utilizing only one wavelength to capture the temperature of the surface or object accurately. However, any form of interference during the measurement could throw off the accuracy of the measuring device which operates on only a single wavelength and the temperature is measured depending on the IR energy amplitude radiated by the device.
2) Multi-variant Sensor
The multi-variant sensor IR thermometer is another type of model using IR rays in its temperature measurement. Such a device manipulates different wavelengths for greater accuracy in any temperature reading.
3) Ratio Sensor
The ratio sensor thermometer is designed to handle two different wavelengths for greater accuracy despite obstructions and interferences in its path.
These infrared thermometer models manipulate different advanced technologies to cater to the different user and application requirements.
Requirements in Selection
When selecting the best of infrared thermometers, one of the important factors of consideration before a purchase is the purpose of use. Industrial environments would want a model that is suited for heavy duty work while domestic consumers may want a model that suffices in measuring food temperatures or indoor heat temperatures.
Different groups of consumers have different purposes for an infrared thermometer which leads to the different types or models to be considered for purchase. Consumers must be clear about their specific requirements for an infrared thermometer to avoid buying a ‘white elephant’ which would not be used or one that is not capable of handling higher ranges of temperatures.
Another requirement of the best infrared thermometer is the wide temperature range the measuring device offers as different thermometers offer different measuring ranges for different applications and environments. Some thermometers are specifically designed for limited ranges while others are intended to measure extreme high and low temperature ranges.
Optical resolution is another important requirement in choosing the best of IR thermometers. This refers to the ratio or field of view of the thermometer. The relationship is that the greater the distance or field of view to be measured, the more accurate the temperature reading using the infrared thermometer. Hence, a more accurate reading of the surface temperature must have the entire surface fall in the full field of view of the IR thermometer. The optical resolution of the IR thermometer could be displayed as a laser point as the area center of focus or the entire area that is measured.
The next factor of consideration in purchasing a good IR thermometer is the measuring device’s strength and power is detecting the emissivity of the object. Every object to be measured would emit or radiate its molecular energy through vibration. Dull or black surfaces emit higher radiation while more reflective materials offer lower emissivity. Good IR thermometers must have an adjustable emissivity feature to detect the temperatures of most objects targeted.
As IR thermometers are designed to measure temperatures of targeted objects without any physical contact, it is important to draw up a specific checklist for a purchase. Such a measuring device is highly useful where conventional thermometers cannot function effectively.
IR thermometers could be applied in various fields and environments including plastic, metal and ceramic which prove to be a challenge to conventional thermometers. The preferred IR thermometer is the model that is comfortable in the hand for a good grasp and safe handling. The handheld device should be practical and affordable to consumers while satisfying the simple and common requirements which most domestic and commercial users would have.
1) Medical Environment
The medical environment is a very volatile environment with infrared technology where the best of technological inventions emerges to assist the medical profession in a wide variety of applications. The IR thermometer is highly preferred in taking body temperature from energy emitted through the ear than other parts of the body.
2) Cooking Environment
It is not surprising that more and more chefs are measuring food temperatures using IR thermometers to ensure the best of servings to their gastronomical patrons. The laser beam from the IR thermometer detects the temperature of foods precisely to determine if the food is properly cooked for the palate.
The laser beam does not pierce the food surface but picks up the radiation heat to help chefs determine the quality of their foods cooked. This device is also useful in maintaining the optimal temperatures of refrigerators and pantries.
