Trade Reviews
As an electrician, finding hotspots in consumer units used to be a guessing game. The 512x384 resolution on this thermal imaging camera is incredible for the price. Spots overloaded circuits instantly.
Brilliant bit of kit. We use it for building surveys to check for missing cavity wall insulation and damp. The fact it works on both my work Android and personal iPhone is a massive bonus.
The image quality blows my old entry-level FLIR out of the water. The 25Hz refresh rate makes scanning a whole room so much smoother. Only dropping a star because I have to take my thick Otterbox case off to plug it in.
Purchased for veterinary diagnostics to spot inflammation in horses' legs. The <40mK sensitivity is superb, picking up very subtle heat differences. Highly recommend for professional use.
Great thermal camera for mobile phones. I use it for automotive diagnostics-checking misfires on exhaust manifolds. It does drain the phone battery a bit if you leave it running for an hour, but for quick checks it's perfect.
Next day delivery was spot on. Used it immediately to find a leak in a customer's underfloor heating system without digging up the whole floor. Paid for itself on the first job.
How to Use
- Download the free DuoThermal app from the Apple App Store or Google Play Store.
- Remove any thick protective cases from your smartphone to ensure a flush fit.
- Plug the camera directly into your phone's charging port (use the included adapter if switching between USB-C and Lightning).
- Open the app; it will automatically detect the camera and display the live thermal feed.
- Select your preferred colour palette, adjust emissivity settings for your target material, and begin your inspection.
- Use the app to capture photos, record video, and generate instant PDF reports for your clients.
At DuoThermal, we understand that modern UK tradespeople and building inspectors need reliable, high-performance diagnostic tools that don't weigh them down. Traditional standalone thermal imagers are often bulky, incredibly expensive, and cumbersome to integrate with digital client reports. That's why we developed a professional-grade thermal imaging solution that leverages the powerful technology already sitting in your pocket.
Our flagship smartphone thermal cameras bridge the gap between entry-level gadgets and £1,000+ standalone units. By delivering a massive 512x384 TISR super resolution, a smooth 25Hz refresh rate, and hyper-sensitive 40mK detection, we provide the clarity needed to spot hidden damp, electrical hotspots, and HVAC inefficiencies instantly. We also know that modern teams use a mix of devices, which is why our system offers true cross-platform compatibility for both iPhone iOS and Android USB-C workflows.
Based in the UK, we are committed to providing exceptional customer support, rapid domestic dispatch, and comprehensive warranties. Whether you are an electrician tracing a faulty circuit, a plumber locating an underfloor heating leak, or a surveyor conducting a property inspection, DuoThermal gives you the professional edge to diagnose faults faster and more accurately.
