Supplied with complete accessory kits and durable hardware, the GP-300C is a reliable Measurement Digital Microscope. Digital Measuring Microscope enables easy system integration and on-demand function expansion, producing sharp, high-contrast microscopic images under diverse observation modes. The ergonomically-designed rigid frame reduces operator fatigue during extended-hour inspection work. Its modular-design supports customized functions and lowers subsequent upgrade costs, delivering strong adaptability for various industrial-inspection and analytical tasks.
The camera module is integrated into the microscope main unit, outputting real-time microscopic images for convenient observation, recording and analysis.
Precision multi-layer lens optical path delivers sharp, clear images to meet requirements for fine-detail observation and precision inspection.
The focus knob works stably together with the lens barrel for smooth, uniform focusing and minimized image shake.
Thick square cast-iron base paired with stainless-steel lifting pole ensures stable placement free of vibration during long-duration observation.
Blue-black metal body with minimalist vertical design, combining modern-tech texture and strong professional-industrial recognition.
Standard ring-light source provides even, soft illumination. Widely deployed for industrial inspection, material observation, teaching-research and quality-analysis work.
Digital CCD imaging replaces traditional eyepieces. Captured images can be saved, compared and post-processed via supporting PC software.
Electronics Industry: PCB circuit boards, FPC flexible circuits, solder joints, pins and chips; inspect cold-solder defects, oxidation, scratches and pin deformation.
Hardware & Cutting Tools: Drill bits, milling cutters and metal parts; check cutting-edge chipping, scratches, burrs, abrasion and surface micro-cracks.
LED & Plastic Molding Parts: LED chips, plastic components and die-cut products; detect notches, stains, rough edges and tiny foreign particles.
Precision Components: Connectors, terminals and spring parts; observe micro-gaps and crimping status; perform pixel-level length and pitch measurement.
Incoming & Shipping QC Documentation: Capture photos for archives, record defective products, export official quality-inspection reports.
Calibrated with a standard resolution target to fully record imaging sharpness at both the center and edge of the field-of-view. Equipped with a 14-megapixel image sensor, it outputs 1920 × 1080 high-definition images via lossless high-speed HDMI transmission.
Focus-stability calibration is performed on textured PCB boards and metallic workpieces. It supports high-precision fine-tuning and is well-suited for high-magnification observation scenarios.
Under stable laboratory conditions, the same feature is measured 10 consecutive times with strictly-controlled reading fluctuation. It achieves high measurement accuracy of 0.002-0.005 mm *(subject to calibration, magnification and sample conditions)*, complying with industrial-precision-inspection standards.
Clear imaging is verified across the continuously-adjustable 21-150 × full magnification range at standard working distances, satisfying high-magnification observation of tiny details.
Adopts direct HDMI transmission interface for real-time lag-free image display. The standard ring-light source provides uniform fill-light to clearly present workpiece micro-features.
Supports adjustable magnification from 21 × to 150 ×, ideal for observing tiny pins, micro-cracks and miniature precision parts with ultra-fine details.
Equipped with 14-megapixel sensor and 1920 × 1080 full-HD resolution; lossless HDMI transmission delivers lag-free, delicate real-time images.
Delivers measurement accuracy of 0.002-0.005 mm *(Smaller measurement tolerance is achieved under higher magnification)*, suited for dimensional inspection of precision hardware, electronic components and mold accessories.
HDMI interface enables direct connection to display screens without PC host hardware, simplifying wiring for on-site workshop-floor operations.

Traditional metallographic microscopes require an extra industrial camera, adapter and external monitor to display live-view images. The GP-300C integrates a high-definition imaging sensor, so clear real-time pictures can be shown directly on the built-in screen. No complicated additional hardware installation is needed.
Unlike basic optical metallographic microscopes that only support visual observation, the GP-300C is compatible with professional measurement software. You can complete dimension measurement, image capture, data recording and offline sample analysis on your computer. Inspection reports can be exported conveniently for quality-control archives.
Conventional metallographic microscopes need frequent manual optical adjustment, and operators usually require long-term training. With the user-friendly interface of GP-300C, users can quickly finish observation and measurement tasks. It cuts down training time for new-comers and improves daily inspection efficiency.
Standard metallurgical microscopes are mostly large-sized desktop optical devices, mainly designed for laboratory-use. The compact-bodied GP-300C fits more application scenarios, including on-site electronic repair, production-line sampling inspection, component checking, teaching research and material-surface analysis.
