As a professional HVAC technician with over a decade in the trades, I have learned one thing above all: having the right tool isn’t just helpful – it’s critical. Especially when you’re chasing down elusive issues like air leaks, moisture intrusion, or thermal inefficiencies that aren’t visible to the naked eye. In these cases, thermal imaging becomes an indispensable extension of your senses.
Recently, I had the opportunity to test out the Thermal Master Thor 001, a professional-grade thermal imaging camera designed for contractors, inspectors, and technicians who need reliable diagnostics in the field. After several weeks of use, I can confidently say this tool has earned a permanent place in my truck.
First Impressions: Built to Last
The Thor 001 ships in a rugged, foam-lined hard case that immediately signals durability. The camera itself is compact but noticeably weighty – a good kind of weight that suggests solid internal components and attention to build quality. From the moment I picked it up, I could tell this was not a flimsy or hobby-grade device.
The design is user-friendly right out of the box. With no manual in hand, I was able to power it up, slide open the lens cap, and start scanning within seconds. The software boots quickly, and the default infrared color palette (black = cold, red/orange = hot) is intuitive and easy to interpret on the bright 3.5" display.
Performance in the Field
The Thor 001’s 3.5-inch display is crisp, and the thermal contrast is sharp enough to distinguish temperature differences across surfaces instantly. It offers a broad detection range from -4°F to 1022°F, more than sufficient for everything from HVAC diagnostics to electrical inspections and beyond.
Capturing thermal images is as simple as pulling the ergonomic trigger. One pull captures; a second saves the image to the included 32GB microSD card. Image transfer to a computer or phone is quick and straightforward via USB-C, but there's also built-in WiFi functionality if you prefer wireless transfers (I personally didn’t test this feature extensively, as wired transfers worked just fine).
What really sets the Thor 001 apart is its fusion-imaging feature, allowing you to overlay the thermal data on a standard image. This gives an immediate sense of physical context – especially helpful when diagnosing leaks inside walls or mechanical rooms filled with equipment.
Real-World Applications
In just a short time using this tool on service calls, I’ve already seen its value firsthand in a number of ways:
Pinpointed a refrigerant leak on a rooftop unit – something even my $1,000 electronic sniffer failed to detect. The subtle temperature change around a pinhole leak made it easy to locate visually.
Identified multiple small air leaks in a commercial building – within minutes. These would’ve taken far longer to isolate by hand.
Tracked the true source of a roof leak, avoiding an unnecessary teardown of a suspect rooftop HVAC unit.
Verified pump and valve operation in a hydronic heating system by checking real-time heat distribution.
These are just a handful of early wins, and I’m confident I’ve only scratched the surface of what this device can do.
Battery Life, Storage & Extras
The battery life clocks in at around 10 hours, which easily gets me through a full workday. The device charges via USB-C, and again, the included 32GB microSD card offers plenty of storage for thermal images and video. There’s also a standard ¼” tripod mount, which may come in handy for long monitoring sessions or when working solo in a stationary environment.
Final Verdict: A Must-Have for Any Serious Tech
I’ve worked with thermal imaging equipment before – mostly bulky, expensive units reserved for large-scale energy audits. Compared to those, the Thermal Master Thor 001 is a breath of fresh air. It’s compact, fast, intuitive, and loaded with pro-level features, all at a fraction of the cost.
This isn’t just a flashy tool for show – this is a true diagnostic asset that helps you work faster, smarter, and with more confidence. Whether you're troubleshooting hydronic systems in winter or chasing refrigerant leaks in summer, this tool is ready year-round.
The Thor 001 carries an MSRP of $649 (currently on sale for $599). Thermal Master does offer a more affordable version called the Thor 002 for $399 which still offers many great featuers, but lacks the macro lens of the Thor 001. Learn more about the Thor 002 here.
You can save 5% on the Thor 001 or Thor 002 if you use the discount code TMTHOR002. Code works on Amazon or the Thermal Master store.
If you're a serious technician, inspector, or contractor looking to up your diagnostic game, I wouldn’t hesitate to recommend the Thor 001. It’s worth every penny for the time and guesswork it saves on the job.

Love how you test things under real conditions, not just lab demos.
I mostly do commercial roof inspections and started with a FLIR C5 thermal camera.
It did okay for big water intrusion spots but really struggled to pick up small leaks early on.
After switching to Thor001, it became a lot easier to spot temperature differences caused by minor moisture infiltration.
Last month I found a small roof leak that only caused about a 4 degree Fahrenheit temperature drop, something the C5 completely missed.
The 512×384 resolution combined with 9-point temperature tracking made the detection fast and reliable.
Also, the rugged build handled rooftop work way better than I expected.
Thor001 really helped me find leaks before they turned into full blown disasters.
Seeing your post reminded me—I actually saw a review about this on TDWorld before too.I live in Sarasota, and my roof is one of those 20-year-old low-slope ones. It's been leaking forever and it's driving me insane.Replace the whole roof? Yeah, sure—maybe if I hit the lottery. There's just no way I can afford that right now.I’ve already gone through 3 gallons of Henry’s roof sealant, covering every crack I could find, even the spots that just looked kinda suspicious.And guess what? Still leaking.I was seriously on the verge of losing it.After reading your review, I decided to give the Thor001 a try.
What I needed wasn’t just to see where the water ended up—I needed to figure out where it was getting in.The resolution on this thing is seriously impressive, and being able to play back and analyze the footage gave me the confidence to know exactly what I was dealing with before I started tearing into the roof.I finally found the actual source of the leak, patched it up, and for the first time in months—no water coming in.No roofing crew, no $5,000 bill.The Thor001 paid for itself on day one.Huge thanks for recommending it—it honestly helped me solve a problem I thought I was stuck with forever.
The Thermal Master Thor 001 seems like a solid tool for quick diagnostics, but I’m curious about its accuracy in different temperature ranges. Have you had a chance to test it in extreme cold or heat?
As an HVAC beginner, I’ve found that a thermal imager is an incredibly useful tool. I had only heard of FLIR before, but it's quite expensive. Does anyone know where this Thermal 001 comes from?
Gotta admit, that Thor001 is slick.
Went to check out a used F-150 and decided to bring it along just in case.
Scanned the engine bay and found a hotspot near the alternator running about 40 degrees hotter than it should have been.
Seller acted surprised, but I walked away from that deal.
Probably dodged a three grand repair bill.
Pretty damn clever use for a thermal camera. TY for putting that idea in my head.

Wow, 40 years of experience in infrared technology, that’s really hardcore! You’re still so knowledgeable even after retirement, I’m really impressed. I’ve been looking into installing a surveillance system for my old house recently. The model you mentioned, does it really outperform high-end ones by a mile? Could you send me a link? That way I won’t have to waste time and money on trial and error.
The Thor 001 is a solid, pro-grade thermal camera. Clear images, easy to use, and great for HVAC, leaks, and inspections. Worth the price—highly recommended!
Been running the THOR001 on a couple of calls lately, mostly to spot airflow issues and verify line temps. For something in this price range, I gotta say—it's surprisingly capable.
Thermal resolution isn't top-tier like FLIR E-series, but more than enough for duct leaks, breaker hotspots, and coil checks. I like how fast it boots and how lightweight it is—easy to carry without babying it. The color palettes are basic but usable, and the temp readings seem reasonably accurate when I double-check with my contact thermometer.
Wouldn't call it my main tool just yet, but it’s turning into a very handy backup. Anyone pushed it in freezing outdoor jobs yet? Wondering how it handles cold startups.
I’ve used the THOR001 a few times around –10 °C. Cold-start takes about 3–4 seconds—basically the same as at room temp. Lens fogging happens occasionally but clears within 30 s without affecting readings. Battery life does drop a bit; a 3 000 mAh pack lasted 1 h 20 min at –5 °C before the low-battery warning, roughly 20–25 % shorter than usual. Carry a spare in an inside pocket and swap as needed. It handles light frost fine, but I wouldn’t leave it out in rain or snow for long—it’s only IP54.
