    I’ve been wanting a thermal camera for a while. The first one arrived with shipping damage. I ordered a hard backed, foam padded case from that huge outdoor store. It was half as much as I found here and they show the size in the listing.

    The image is a little small, but it does the job well. The on/off button has to be held down for ten seconds or more. It’s a little annoying, but doable. The images help me in my diagnosis and the screen shows the temp which is helpful. I use this in my laundromat to diagnose machines and in my electronics repair hobby.

    I replaced an ignitor on a dryer, turned it on and before I could verify it was working by touch, I could see on the Flir that it was already heating up.

    I tried to use it on my OLD home looking for air leaks, but couldn’t find anything. I probably need to get much closer to windows and doors. I was assuming I could see heat coming out from 20-30 feet away and I don’t think that’s going to happen.

    It works. Actually I think it does pretty good. I think I’ll give it 4/5, just because it isn’t the best technology anymore. There are multiple applications I have discovered since purchasing. Like engine diagnostics. And locating shorts, heat loss…

    Overall good product. Size of the pictures taken are the same size as the screen. If they upped the resolution it would be perfect. Attached is my dog and a present from her. Thanks!

    So many possibilities with this. You can see hot spots on a circuit board, insulation issues on the house or in plumbing. Check to see if someone has a temperature. The more you use it the more uses you find for it.

    Defiantly a budget friendly thermal cam! Gets the basic aspect of the job done and is very user friendly/simple to operate.

    Golden Review Award: 4 From Our UsersFirst thing I used it for was scanning our home breaker panel and found a loose breaker connection. In my professional career I used a number of expensive test and trouble shooting devices in Healthcare facilities management and this affordable device along with other devices i.e. an ultra sound detector, gas detector, temperature detector which I have purchased through Amazon and they perform as well as high price industrial devices.

    The only things I wish is that it was a video type of camera but we use it at ever paranormal investigation we go to.

    Golden Review Award: 13 From Our UsersSo far I am very pleased, and had the unit up and running in short order. I’ve already verified where insulation was missing around some light fixtures, and interesting hot spot where the ceiling and wall meet… The only issue I’ve noticed is that the image quality is really low resolution. You can resize and upscale them, using some photo software. Flir does have a free software that you can make reports from the photos. The version that would make the photos better, and provide features, is a few hundred dollars.

    Golden Review Award: 13 From Our UsersThis is a great intro-level thermal imaging camera. The image quality is not great, but you shouldn’t expect much better from a camera in this price-point. I used it to find air-leaks in a building envelope, and it worked perfectly.

    Golden Review Award: 21 From Our UsersThis review is on first impressions, as I’ve only had it one day. I can say I am absolutely impressed with the quality of this camera. I bought this, primarily, to find hot spots in my house so I can insulate accordingly. I live in Arizona and have several areas in my home that stay noticeably warmer than others. Right out of the box, I was able to find multiple areas that are uninsulated. In fact, some areas I was actually able to see the studs behind the wall because of the stark temperature difference between outside and my inside temp. The settings are very user friendly, so I was able to customize within a few seconds. I researched this product for a while before taking the plunge and considered cheaper alternatives. However, I think the price was well worth it. I couldn’t imagine getting more of my money’s worth.

    Golden Review Award: 31 From Our UsersIt was better then expected..pictures are of ceiling with a square light, one with a camera other with FLIR TG165 . I did not have to resort to the user manual to operate it which is very important to me.. Im one of those guys that will read the instructions only if i have to… Easy menus to set date and other parameters… the ceiling shot shows the framing above the ceiling on how the light was mounted and looks. I was able to find hidden heat sources that i was not aware of.. had a shredder in stby mode and it was cool to the touch everywhere but apparently not the case internally there was a spot showing significant heat, same with transformers, some normal some excessive.. $350 bucks is a lot for my budget but well worth it.. I asked FLIR as an entry level which is better for application I was going to use it for FLIR ONE or TG165 and the answer was quick the TG165. Well I have not had any other thermal camera so cant may reference but Im glad I bought it..

    Golden Review Award: 17 From Our UsersI purchased this to use in classes where we teach about machinery modification for lubrication best practices as it relates to equipment reliability. The first class I took this too was blown away when they could see why they were having oxidation issues and where their critical gearboxes were storing heat. I knew that thermography would have a good impact on the training, I just didn’t realize just how much of a difference it would make to the students for actually having the tool in their hands while going through the class.

    I will say that I wish I had sprung for the E6, but at the price point this tool definitely does an outstanding job. I would highly recommend for anyone trying to get started in thermography and especially for anyone running a lubrication program inside a manufacturing facility.

    Golden Review Award: 2 From Our UsersI bought this device to trace a building walls humidity since the humid part of a wall will have a lower temperature than the rest of it. I found that the numerical readings of the thermometer show this difference in tenths of a degree Centigrade but the color display of the device is not accurate enough. May be I should choose a device with a higher level of display FLIR TG165 Spot Thermal Camera accuracy but theese do not fit my budget.
