High-Temperature Thermography for Advanced Industrial Inspection

The HIKMICRO G61H Thermal Camera is built for professional users who need high-resolution thermal imaging, accurate temperature measurement, and advanced inspection capability across both general and high-temperature applications.

Its 640 × 480 infrared detector, SuperIR image enhancement, 50 Hz image frequency, and multiple focus modes help technicians capture clear thermal detail across a wide range of inspection tasks. The extended measurement range up to 2000°C makes it especially suitable for furnaces, kilns, refractory inspection, foundries, metal processing, glass manufacturing, process heating, and other demanding industrial environments.

With radiometric image capture, video recording, annotation tools, wireless connectivity, HDMI output, GPS, compass, laser distance measurement, hot-swappable battery support, and rugged field-ready construction, the G61H is a strong choice for industrial maintenance, predictive maintenance, electrical inspection, mechanical diagnostics, HVAC, oil and gas, utility, power generation, and high-temperature process applications.

G61 vs G61H – What Is the Difference?

The HIKMICRO G61 and G61H are very similar in camera platform, image quality, and professional inspection features. Both models use a 640 × 480 infrared detector, SuperIR image enhancement up to 1280 × 960, 50 Hz image frequency, 25° × 19° field of view, 8 MP visual camera, 4.3" touchscreen, multiple focus modes, Wi-Fi, Bluetooth, USB-C, HDMI, GPS, compass, laser distance measurement, and advanced reporting features.

The main difference is the temperature measurement range. The standard G61 is designed for high-resolution general thermography with measurement up to 650°C, making it suitable for HVAC, electrical, mechanical, building, utility, power distribution, and standard industrial inspection work.

The G61H is the high-temperature version, extending measurement capability up to 2000°C. This makes it the better choice for furnace inspection, kiln monitoring, refractory inspection, foundries, metal processing, boilers, burners, glass manufacturing, molten material monitoring, and other high-temperature industrial applications.

In simple terms, choose the G61 for high-resolution general inspection work, and choose the G61H when the application requires very high-temperature measurement above the standard 650°C range.
