Description
The GDIR-640 is a professional-grade, field-optimized handheld infrared thermal imagerexclusively designed for non-contact temperature measurement and fault diagnosis of electrical and industrial equipment. It fully complies with DL/T 664-2016, IEC 62446-1:2016 and GB/T 19870-2018 standards, adopting a high-performance 640×480 uncooled focal plane array (FPA) infrared detector with ≤50mK thermal sensitivity, which can capture extremely subtle temperature differences and clearly display thermal anomalies.
The instrument features a dual-spectrum design integrating a 500-megapixel visible light camera, supporting four imaging modes: infrared only, visible light only, dual-spectrum fusion and picture-in-picture. The advanced fusion algorithm perfectly overlays thermal information with visible light details, making it easy to locate fault positions. With a wide temperature range of -20℃~600℃ (extendable to 1600℃) and ±2℃/±2% measurement accuracy, it meets the testing needs of various power equipment. It supports 1 global + 8 local temperature measurement objects (points, lines, rectangles), automatic high/low temperature tracking and customizable threshold alarms. The built-in laser pointer accurately indicates the target position, and the voice/text annotation function facilitates on-site record keeping. With IP54 dustproof and splashproof rating and 2-meter drop resistance, it can work reliably in harsh field environments. The dual-battery design provides up to 8 hours of continuous operation, making it ideal for all-day on-site inspections. Ideal for substation equipment inspection, transmission line detection, distribution network maintenance, industrial equipment fault diagnosis and building energy efficiency testing.
