G Series G41H

G Series G41H – High-Performance Thermal Imaging Camera for Extreme Temperatures

Introduction

The G Series G41H is a premium industrial thermal imaging camera built for high-temperature applications, capable of measuring up to 2000°C (3632°F). With high-resolution thermal imaging, advanced measurement tools, and radiometric video capabilities, it is ideal for industries such as metallurgy, power plants, and research facilities.

Main Description

The G41H features a 480 × 360 IR sensor with SuperIR up to 960 × 720 pixels, providing exceptional thermal detail. The NETD is <35 mK, delivering excellent thermal sensitivity, while the 50 Hz image frequency ensures smooth and precise imaging. The detector pitch is 17 μm, with a focal length of 25 mm and F1.0 aperture, resulting in a field of view of 18.7° × 14° and spatial resolution of 0.68 mrad. The camera supports Laser Assisted AF, Continuous AF, AF, Manual Focus, and Touch AF, achieving focus in approximately 2 seconds with a minimum focus distance of 0.3 m (0.98 ft).

Images are displayed on a 4.3" LCD touch screen (800 × 480) with manual or automatic brightness adjustment. The camera supports Infrared, Visual, Fusion, PIP, and Blending modes, along with multiple color palettes such as White Hot, Black Hot, Rainbow, Ironbow, Red Hot, Fusion, Rain, and Blue Red. Color alarms include Above, Below, Interval, Insulation, and Condensation detection.

The G41H measures object temperatures from -20°C to 2000°C (-4°F to 3632°F) with ±2°C / ±2% accuracy. Measurement tools include Center Spot, Hot Spot, Cold Spot, and user-definable options: Delta T, 10 spots, 1 line, 5 rectangles, and 5 circles. It also supports inspection route planning and Level/Span adjustment via Auto, Manual, or 1-Tap touch-screen.

Data is stored on a removable 64 GB Micro SD card, with a capacity of ~60,000 images. Videos are saved in MP4 format and radiometric video, with UVC and Wi-Fi streaming available. Users can annotate images with voice notes (up to 60 seconds) and text notes (up to 200 characters).

Additional features include a 3264 × 2448 visual camera (8 MP), LED lighting, a Class II laser pointer (635 nm, <1 mW), and a laser distance meter (50 m indoor / 10 m outdoor). The G41H is equipped with GPS and compass, enhancing field usability.

The camera is powered by an interchangeable rechargeable Li-ion battery, providing 4 hours of operation and 4 hours to full charge. Built to withstand tough environments, it has IP54 protection, can survive a 2 m drop test, and meets strict safety, EMC, vibration, and shock standards.
