10 Best Thermal Leak Detector 2026 in the United States

The FLIR TG298 thermal imaging camera is designed for industrial use, especially where detecting high-temperature spots quickly is important. It features a super resolution mode that improves image clarity by upscaling from 160x120 to 320x240, making it easier to spot thermal leaks or issues. The built-in visual camera with 640x480 resolution and MSX technology adds real-time detail, which helps users interpret images without needing expert knowledge. The laser pointer shows exactly where the temperature is being measured, simplifying targeting for faster detection.

The digital display is clear, and the device is battery powered with two rechargeable lithium-ion batteries, making it portable and convenient for fieldwork. USB connectivity allows easy file transfers, which is handy for logging and reviewing temperature trends. The rugged plastic outer shell adds durability for industrial environments. Its weight and size make it comfortable to hold, and the included accessories like wrist strap and pouch enhance ease of use.

This camera suits professionals needing a durable, user-friendly tool for spotting thermal leaks and faults quickly in demanding industrial settings. While the resolution, enhanced by super resolution, may still feel limited compared to higher-end thermal cameras when very fine details are required, having spare batteries can support longer shifts.

The Fluke TiS75+ thermal imager is a rugged and reliable tool designed to handle tough environments, making it a strong choice for professionals who need a durable thermal leak detector. It can survive drops up to 2 meters and has water and dust resistance (IP54), so it’s well-suited for on-site inspections where conditions aren’t always ideal. The device supports battery-powered operation with an included lithium-ion battery.

In terms of usability, the TiS75+ shines with its smart asset tagging and voice annotation features. These make organizing and reviewing thermal images easier by allowing you to link images directly to assets using QR codes and add real-time notes, saving you time and improving inspection accuracy. The user interface is straightforward, which helps those who want to quickly set up preventive maintenance routines.

The Fluke TiS75+ is ideal for users needing a tough, user-friendly thermal imager to support preventive maintenance programs and asset monitoring. It may not be the best fit if you require very specific technical details upfront or advanced connectivity features.
