A big tip about using the Seek Thermal SHOT portable thermal imager - a thermal imager that will help you detect and eliminate heat or cold leaks, notice problems with electrical wiring, see places of local heating or overheating of equipment, find prey while hunting, and so on. Seek Thermal has managed to create an inexpensive and affordable compact standalone device that has the full functionality of "adult" professional models.
Greetings!
I already had a review of the younger model , which works as a prefix to a smartphone, this time an autonomous thermal imager fell into the hands with display, visible range camera, with Wi-Fi module. The resolution of the thermal matrix is ββ206 x 156 pixels. The thermal imager is useful for monitoring the temperature difference and timely identification of problem areas.
The comments asked about the cost: with code HSHOT (10% discount on the entire Seek Thermal line) Shot price is 44910 rubles.

There are many application scenarios - from a simple inspection of the apartment and bypassing the house from the outside to searching for faulty radio elements, checking electrical equipment, and even for hunting and security. The advantages of the all-in-one combine, that is, in a thermal imager in a rugged housing (IP54) with a display, built-in functions for analysis, with an additional visible range camera, are obvious, for example, you do not need to have a special smartphone with you to connect to a thermal imager-attachment , as with the Compact-series.
The Seek Thermal Shot does not need to be connected to a smartphone to work - it is a standalone device. The display resolution is convenient for operation. Using the touch screen, it is convenient to control the device, set markers to determine the temperature, highlight the areas under study, and so on. The screen resolution is 640 x 480 pixels. The body of the device has rubber inserts and is generally protected from dust and moisture according to the IP54 standard. When compared with , then the latter has a higher resolution of the thermal matrix (320 x 240 pixels).
The kit includes a lanyard and a cable for synchronization and charging (USB-C).
There is also a detailed instruction in Russian for all the functions and terms of the device.
Appearance of the Seek Thermal Shot thermal imager.
Below is a USB-C connector (under a rubber plug), a thread for mounting on a photo tripod (1/4β³).
On the top panel (closer to the center) is the power on / off button and on the right is the shooting button.
Unlike the Flir C2 / C3 models, the Seek Thermal Shot / Shot Pro line has a larger display (3 inches versus 3,5) and the visible range matrix resolution is 640x480 for Shot versus 320x240 for Flir. On the body there is a lens with a special IR lens for a microbolometer, a little lower there is a window for the matrix of the visible range. On the left is the backlight. The Seek Shot has a battery life of about 4 hours. Such a capacious battery allows you to work for a long time at low temperatures (in the cold).
For convenience or for long-term observation of the object, it makes sense to install the thermal imager on a tripod. For this, a standard thread on the body (1/4β³) is provided. There is also remote access via Wi-Fi.
Under the rubber cap is a USB-C connector for charging and synchronizing with a computer.
The body is rubberized, not slippery, the inserts protect against small bumps. At the bottom there is a hole for a lanyard.
The backlight is turned on from the menu, you can use it as a flashlight.
Press the power button, turn on the device.
The photo shows one of the saved images - during operation, the images are saved to the internal memory and are available for further analysis, including on the device itself.
One of the first shots is checking the heating of the lightbox backlight lamps. Seek Thermal Shot allows you to analyze images directly on the device. You can choose a palette, select a marker (point) or image area and evaluate the temperature. The lamps are made of aluminum profile and give off heat well to the surrounding space. Average temperature during long-term operation: 40β¦50 Β°Π‘.
For quick analysis, it is convenient to apply one of the contrasting color schemes (palettes). Several palettes are available: White, Black, Tyrian, Spectra, Iron, Prism, Amber and Hi (contrast).
One of the killer functions of this model of thermal imager is the ability to combine the visible and thermal images for detailed analysis with the overlay of temperature markers.
Thermal imager files: thermogram plus combined image.
The thermal imager is equipped with a Wi-Fi module and is capable of broadcasting an image to a smartphone or tablet (Wi-Fi Streaming) using .
We activate the Wi-Fi access point (the password and login are configured).
We connect to the created access point.
The Shot thermal imager allows you to accurately measure surface temperatures in the range from -40Β°C to 330Β°C, including remotely (via Wi-Fi), plus analysis tools are available (palettes, markers, area, and so on).
The very fact that it is possible to save an image for further analysis gives the SHOT line a huge advantage. You can take a series of shots for comparison and calm analysis.
Sample image from memory - all temperature marks are saved, plus post-analysis is available.
An example of overlaying a visible image and a temperature image.
Let me turn directly to specific examples - a thermal inspection of a residential multi-storey building was carried out in order to search for heat leaks.
An average panel house was chosen. The problematic joints of panels with unsealed seams are clearly visible. The people, as best they can, insulate it themselves, or with the services of the housing department (red seams are insulation with polyurethane foam).
Naturally, everything βshinesβ with heat outward. Precious heat can leak through such seams, you can wind the heating meter, mold can form in these places.
An example of external insulation.
The tenants used the services of insulation - they covered the cracks from the outside and sheathed them with foam sheets.
The picture shows the temperature difference - an insulated place radiates less heat than a standard panel.
An interesting point was discovered in the transition-arch in the house.
The joints have practically no thermal insulation, in such cases adjacent walls freeze through in the apartment, mold appears, the room temperature is kept at +15 degrees and so on. In such cases, it is necessary to insulate thoroughly, both from the outside and from the inside at the same time.
Now let's examine the entrance from the inside.
The picture shows the result of superimposing a visible image and a thermogram.
Previously, there were complaints - "the entrance freezes through, it's very cold." At the same time, the heating worked (the relevant services believed the heating radiators in the entrance).
The bright vertical tube in the picture is the driveway heating (+31 degrees). Next to the heating return (colder).
One of the obvious reasons for the low temperature is the lack of intelligible thermal insulation of the gas inlet.
This is a hole straight to the street at the level of the second floor, into which cold (frosty) air is blown.
Specifically, the values ββββwere measured: the temperature at the entrance is +12, in the area of ββ\u4b\uXNUMXbthe "leak" minus XNUMX degrees.
That is, it is cold in the entrance due to obvious things. And the heating works as it should - checked!
Another interesting point is the open dormer windows in the basement. A favorite place for stray cats.
I continue with thermoinspection. This time - a heating main (commissioning of heating in the area of ββββa residential building). Specifically, the picture shows local damage to the thermal insulation, as a result, the boiler room βheatsβ the street, and in the house itself it is colder than it could be ...
Next, they asked to inspect a private house.
Heating boiler. The hottest part is the chimney.
The heating boiler itself.
Pipes, heating pump. The refrigerator radiator tubes (vertical tubes) are visible on the left.
An example of a well-functioning heating radiator.
Heating supply pipe.
But I found a problematic radiator - there is dirt inside, it interferes with normal heat transfer and water flow. There were complaints about uneven heating.
By the way, the software allows you to evaluate the range of temperature values. To do this, select the appropriate icon in the menu and select an area on the screen. The minimum and maximum values ββare displayed, and the average temperature in the selected block is calculated.
And it is also possible to fix the temperature boundaries - this allows you to select objects with a minimum temperature difference.
An example of such a photograph is a thermal trail. The "fix" temperature is set to 10 degrees (from 17 to 28 degrees).
I continue to inspect the house.
In words, the client said that, despite good heating (an imported boiler, good radiators, a circulation pump, plus plastic windows and double-glazed windows), the house is cool. This became especially noticeable after the onset of cold weather.
What can I say - the house is "hot". When building a house, they βgot it wrongβ or βsaved itβ - they chose the wrong type and amount of heat-insulating material. Frame house, insulation inside, OSB outside. The surface temperature reaches +10 degrees, with frost outside minus 10 ... 12 degrees. Alas, the repair will result in a good amount, since you will have to redo the finished one.
Neighboring frame house.
Here the situation is slightly better, the meaning is the same.
Another cottage. Specifically examined the windows.
It was interesting how the skylight was implemented.
The picture shows normal isolation.
A shot from the inside - the glass is cold, but, in general, no leaks were noticed.
But between the levels of the roof, the builders forgot to insulate the joint.
+9 in the picture.
The average temperature is +4.
The outer skin is leaking at the seams.
Skewed windows (not adjusted clamp)
A door with a broken seal ("Blowing out of the door").
The problem is in the office. Complaint: "It blows from the window." The ceiling near the load-bearing wall freezes, most likely the thermal insulation of the seams is broken. Temperature +16Β°C with an average of +26Β°C indoors. In severe frosts it will freeze.
The operation of the heated rear window in the car - you can check and repair faulty heating filaments.
And a similar picture for seat heating.
In general, in a car, you can also check the chassis (worn parts, parts without lubrication - heat up), the engine itself (heat exchange, etc.).
Just interesting photos that I collected during the test.
Water at sub-zero temperatures.
Several pictures of people. Pay attention to the different heat dissipation of different parts of the body - this indicates the quality of winter clothing.
Sewer manhole, warm.
Air conditioning installation.
The other day I checked the work of a 3D printer.
It is convenient to calibrate the temperature of the table and nozzle.
At the end of the article, I will note that the cost of even the most expensive model (Seek ThermalShot Pro or similar) is a meager cost when compared with possible miscalculations when building a house, installing thermal insulation or repairing consequences. The thermal imager will help to identify the malfunction in a timely manner and provide for local repairs. Thermal inspection is a smart action that will save time and nerves when
inspection of a residential building or apartment.
Thank you for your attention, I hope you will also need a thermal imager.
