Why Choose ThermImage UK

See the Unseen with Commercial-Grade Precision

The FLIR TG165-X is the ultimate compact thermal imaging camera for UK trades professionals. Designed to bridge the gap between single-spot infrared thermometers and high-end thermal cameras, this rugged handheld unit dramatically reduces inspection and diagnostic time. Whether you are checking for overheating fuses, inspecting HVAC airflow, or identifying cold bridges in a property, the TG165-X provides a clear, reliable thermal picture of the problem area.

Patented MSX® Image Enhancement

Unlike standard infrared cameras, the TG165-X features FLIR's exclusive Multi-Spectral Dynamic Imaging (MSX®). This technology extracts high-contrast details from the built-in visual camera and embosses them onto the thermal image in real-time. The result is a crisp, easy-to-understand picture where you can clearly read labels, wires, and structural outlines without compromising thermal accuracy.

Built for the British Worksite

Site work demands durable tools. This portable thermal imaging camera is IP54 rated for dust and water resistance, making it perfectly suited for damp basements, dusty plant rooms, and outdoor building inspections. Tested to withstand a 2-metre drop, it is a robust addition to any electrician's, plumber's, or surveyor's toolbag. The intuitive point-and-shoot interface means you can start capturing images and saving data instantly, with no specialist training required.

Bought this primarily as an hvac thermal imaging camera. The MSX feature makes identifying pipes under floorboards incredibly easy. Saves me hours on fault-finding and the next-day delivery was spot on.

Essential kit. Using it as a thermal imaging camera for electrical inspection means I can scan a whole consumer unit in seconds. The bullseye laser is dead accurate for isolating the exact breaker.

Great compact thermal imaging camera for building inspection. Spotted a cold bridge in a cavity wall instantly. Dropped a star because I wish the screen was slightly brighter in direct sunlight, but it's very rugged.

Brilliant thermal imaging camera for leak detection. Found a micro-leak in a central heating system that was buried in concrete. Paid for itself on the first job.

Upgraded from a basic Seek Thermal plug-in. Having a dedicated portable thermal imaging camera is much better for site work. IP54 rating gives me confidence when working in dusty plant rooms.

Rebecca Thompson, LeedsLeeds

A very capable handheld thermal imaging camera. The 80x60 resolution is fine for close-up diagnostics, though for large commercial facades I'd rent a higher-spec unit. Perfect for everyday home inspections.

Dr. Emily Clarke, EdinburghSheffield

The perfect thermal imaging camera for electricians. Fits right in my toolbag. The laser targeting takes the guesswork out of identifying which specific breaker is running hot. Great value for the time saved.
