Infrared Laser Thermometer
An infrared laser thermometer, also known as an infrared thermometer or a non-contact thermometer, is a device that measures the temperature of an object without making direct contact with it. It uses infrared technology to detect the heat emitted by the object and provides a temperature reading on a display.
The basic principle behind an infrared laser thermometer is that all objects above absolute zero temperature emit thermal radiation, which includes infrared radiation. The thermometer has a lens that focuses the infrared radiation emitted by the object onto a detector.
The detector converts the infrared radiation into an electrical signal, which is then processed to calculate the temperature of the object using the Stefan-Boltzmann law, which describes the relationship between an object’s temperature and the amount of radiation it emits.
Some infrared laser thermometers also have a built-in laser pointer that helps to aim the device accurately at the object being measured. The laser pointer emits a laser beam, which is used as a reference to determine the exact spot on the object from which the thermometer is measuring the temperature.
Infrared laser thermometers are commonly used in a wide range of applications, including cooking, HVAC (heating, ventilation, and air conditioning) systems, automotive diagnostics, electrical troubleshooting, industrial process control, and medical applications.

Sight technologies enable the precise application of infrared temperature measurement devices.
Simple, cost-effective handheld laser thermometers utilize a single-point laser pointer to point the middle of the measuring spot with a particular amount of parallax error.
With small measurement objects, in particular, this can lead to the distortion of the measurement result, meaning potentially critical situations are not recognized.
To properly display the measuring spot in its full size, laser thermometers with optical sights were developed which use cross hairs to mark the dimensions, thus allowing precise targeting.
1. Laser Thermometer with Dual Laser
In a dual laser system, two laser beams being emitted from the lens approximately depict the narrowing or widening of the measuring beam from larger distances.
The diameter of the measuring spot is indicated using the distance between the two laser points on its circumference. The simultaneous usage of the video module and a cross-hair marking allows video pyrometers to exactly mark the measurement field.
2. Laser Thermometer with Cross Hair Sight
Thanks to the utilization of the latest laser illumination technologies, it’s possible to represent the measuring spots of infrared thermometers. As an accurately sized cross-hair whose dimensions precisely match those of the measuring spot.
Here, four laser diodes that are symmetrically arranged around the infrared optical measuring channel are equipped with line generators. Which generates a line of a specific length at the focusing distance determined by the lens.
Opposing pairs of projected laser lines fully overlap at the focus point in such a way that they form a measuring cross or crosshairs that precisely depict the measuring spot.
For shorter or longer measurement distances, the overlapping is only partial, meaning that the length of the line and, as a result, the size of the measuring cross will change for the user.
This means a considerable improvement in the practical applicability of devices with good optical performance.
3. Laser thermometer with focus point switching
In the areas of electronic maintenance and industrial quality control, in particular, small measurement objects often need to be measured at short distances (0.75 – 2.5 m).
Here, the development of new measurement devices allows the measuring spot to be focused within certain limits.
In the process, the respective laser thermometers employ a technology during which a twin-lens optical system is often switched to live very small measuring spots by mechanically adjusting the inner lens position almost like macro mode in digital cameras.
If you move closer to or further away from the measurement object, the measuring spot rapidly increases in size.
With the help of two overlapping laser beams that display a laser point diameter of exactly 1 millimeter at the position of the littlest measuring spot.
It’s possible to set both the optimum distance and therefore the optimum measuring spot size.
However, setting measuring spot sizes of less than one millimeter remains a technical challenge even for laser thermometers with focus point switching.

7. Maverick LT-04 Infrared Laser Thermometer
The Maverick LT-04 Infrared Thermometer replaces the LT-03 in their IR lineup. Like most other units of this type, it has a laser to assist in pointing the device at the target.
The display indicates the measured temperature, the min/max temperatures, the scale in use (ºF or ºC), the battery condition, and the laser status (on or off).
The illustration on the instruction sheet also shows a USB and a “cue aware”. However, there is no mention of any alarm feature in the text instructions and there is no USB port on the unit. Dubious documentation, I suppose?
It is difficult to assess the accuracy of IR guns without fancy equipment, so I had to improvise. I pointed the device at a dish of ice water.
A pot of simmering water that measured 205ºF with a conventional thermometer of known accuracy, and the surface of some cooking oil heated to approximately 345ºF. I also pointed to a pan of cooking oil that was at 86ºF.
Actual: IR Reading
32º: 30º
86º: 86º
205º: 190º
345º: 356º
The temperature reading of an infrared thermometer assumes that the emissivity is set correctly for the surface being measured. Most IR thermometers are set for a typical emissivity of 0.95.
That is the setting Maverick uses, but it’s not adjustable. This might be a problem for accurate measurement of a surface with a significantly different emissivity, such as a shiny surface.
The behavior and accuracy seem typical of IR guns I’ve tested. The display is easy to read and the back light makes it easy to use in dim light. You can control the backlight, the laser, and the temperature scale using buttons on the rear of the unit.
Another button toggles between the maximum and minimum readings during the most recent measurement cycle. The instruction sheet is minimal with a few spelling errors, but it is adequate to use the unit effectively.
Buying Guide
Infrared laser thermometers, also known as infrared thermometers or non-contact thermometers, are handy tools for measuring temperature without physically touching the object or surface being measured. They work by detecting the infrared radiation emitted by the object and converting it into a temperature reading.
Infrared laser thermometers have a wide range of applications, including in the kitchen, automotive, HVAC, electrical, and industrial sectors. If you’re considering buying an infrared laser thermometer, here are some key factors to consider in your buying guide:
Temperature Range
One of the most important factors to consider when buying an infrared laser thermometer is its temperature range. Different models have different temperature ranges, so it’s essential to choose one that meets your specific needs.
For example, if you plan to use the thermometer for cooking purposes, a model with a temperature range of -50°C to 300°C may be suitable. However, if you need to measure higher temperatures in an industrial setting, you may need a model with a broader temperature range, such as -50°C to 1000°C or higher.
Accuracy
The accuracy of the infrared laser thermometer is another critical factor to consider. The accuracy is usually expressed as a percentage of the measured value or a specific temperature range. Higher accuracy means the thermometer will provide more reliable and precise readings.
Look for a model with an accuracy of ±1% or better for most general applications. However, for more critical applications, such as in scientific or industrial settings, you may need a higher level of accuracy.
Emissivity Settings
Emissivity is a measure of an object’s ability to emit infrared radiation, and it can affect the accuracy of the temperature readings from an infrared laser thermometer. Different materials have different emissivity values, so it’s essential to choose a thermometer that allows you to adjust the emissivity settings to match the material you’ll be measuring. Some thermometers come with pre-set emissivity values for common materials, while others allow you to manually adjust the emissivity.
Laser Targeting
Most infrared laser thermometers come with a built-in laser that helps you target the object or surface you want to measure accurately. The laser allows you to aim and point the thermometer at the desired spot, ensuring that you are measuring the temperature of the intended area. Look for a model with a clear and visible laser that can be easily turned on and off.
Display and Features
Consider the display and features of the infrared laser thermometer. Look for a model with a clear and easy-to-read display that shows the temperature readings in a format that is convenient for you, such as Celsius or Fahrenheit.
Some thermometers also come with additional features, such as backlighting, data hold, auto power-off, and temperature alarms, which can be useful depending on your specific needs.
Durability and Build Quality
Consider the durability and build quality of the infrared laser thermometer. Look for a model that is made of high-quality materials and feels sturdy in your hand. A durable thermometer will be able to withstand regular use in different environments without getting damaged easily.
Battery Life
Check the battery life of the infrared laser thermometer. Look for a model that has a long battery life and allows you to replace the batteries easily.
Some thermometers also come with a low battery indicator, which can be helpful to ensure that you have enough power to get accurate readings.
Price
Infrared laser thermometers are available at various price points, so consider your budget when choosing a model. While it’s important to find a thermometer that fits your budget, remember that cheaper models may have limitations in terms of accuracy, temperature range, and durability.

Conclusion
Ever wonder what infrared laser thermometers are? I finally did a little research and discovered that these devices measure the amount of heat emitted by an object.
The laser component is merely for aiming, sending out a skinny red beam of sunshine so you recognize where you’re pointing it.
I also found that these thermometers only measure surface temperature. In order they can’t assist you to gauge the doneness of a roast or the other food where you would like internal temperature. I was hoping to also use it to check the temperature of liquids like deep-frying oil or sugar syrup, but the measurements were too inconsistent.
It did, however, work very well for tempering melted chocolate, and if you’re fussy about getting your butter softened to a precise 65°F before baking, this thermometer can help.
