Opinions about FLIR TG165

Main advantage:

It is indicated to record the emissivity of an object, as well as its temperature. In this sense, it offers a reception range of -25 to 380 ° C, which is sufficient for professional data collection.

Main disadvantage:

It is not capable of recording the temperature of objects behind other surfaces, be it marble, cement or the like, so it is only used for direct scanning.

Verdict: 9.8/10

It is one of the most comfortable thermal imaging cameras to use, with a classic design and high performance. In addition, it has an affordable price.

Main Features Explained


It is a practical model, since it has an easy storage system through the use of a removable microSD card. Thanks to this, you can later download the information quickly through the USB cable included in the package or using the card itself. This operation allows you to save images and data for analysis, so you can create diagnoses more easily.

In this sense, it includes an 8 GB micro SD card, so it is capable of storing approximately 75,000 images to start operating immediately, however, you can also expand the memory by purchasing an additional card of up to 32 GB.

It incorporates a function that activates and projects a double line laser, this allows you to more accurately visualize the area where you are going to measure the temperature. Also, it has free focus so you can capture the environment easily and conveniently.

In terms of autonomy, it has a built-in lithium ion battery with a maximum duration of 5 hours using the laser continuously, so it is suitable for use for a full day of work before having to charge it again, however, the charge can be maintained for up to 30 days without any use. Also, you should take into account that it only needs 6 hours of connection to the current to obtain a charge at 100% of its capacity, however, in case you are in a hurry, it can provide 90% with a lesser charging time of only 4 hours. To save battery, you can set its operation so that the camera is active for 1, 2, 5 and 10 minutes, or turn it off manually using the OFF button.


Offers a wide field of view compared to other thermal imaging cameras, with an angle of 50° x 38.6° that makes it easy to read large surfaces, for example, when using it on a wall without having to take multiple images of it surface, but you can capture it completely with a single image.

It is capable of processing the temperature of an object if it is in a range from 25 ° C below zero and up to 380 ° C, which is almost 4 times the boiling point of water, so according to the opinions of some users, this is the best thermal imager as it also has utility in the industrial area of ​​professional measurements.

It has a minimum measurement range of 26 cm, which protects the device from close proximity to a high-temperature object and guarantees its effectiveness. Similarly, you should know that its accuracy is 1.5 °C, so you can perform quality analysis. The graph that it projects is indicated to show the image in bitmap (BMP), with precise information regarding the temperature and emissivity of the object or surface that you decide to analyze.


It has a resistant design, created in this way to withstand the most hostile environments, which are usually those of hard, intense and constant construction work. Consequently, it has a rigid casing that allows it to withstand a fall of up to 2 meters in height.

On the other hand, it incorporates many functions in a simple design that makes it easy to control the device, with only 4 multifunction buttons below the screen and a rigid trigger that activates the camera record. Also, the handle has curvatures so that it can be ergonomically adjusted to the shape of the hand.

The body of this camera is compact, so you can hold it comfortably avoiding fatigue during use, as well as carry it in your pocket or with your tool kit for greater practicality. Its measurements are 18.6 cm long by 5.5 cm wide and 9.4 cm high. In addition, it incorporates a wrist strap that allows you to use it without fear of falling during the measurement. It is worth noting that it offers easy viewing of the thermal image through its TFT LCD screen, which measures 2 inches, providing a resolution of 80 x 60 pixels.
