Unique Design Advantages

Integrated 4K CCD Imaging Design

The camera module is integrated with the microscope main unit, delivering real-time 4K ultra-HD images. It supports photo capture, video recording and dimensional measurement for simultaneous observation and documentation.

4K High-Resolution Optical System

Precision multi-layer lens optical path generates delicate, clear images to capture tiny details of electronic components and satisfy high-precision inspection standards.

Precision Focusing Mechanism

The focus knob works stably with the lens barrel for smooth focusing and minimal image shake.

Robust Metal Stand & Base

Thickened square metal base paired with stainless-steel support pole keeps the unit stable and free of wobble during long-duration continuous-inspection workflows.

Industrial-Grade Appearance Structure

Tough metal body with blue-black color scheme and minimalist vertical design, combining modern-tech aesthetics and professional industrial texture.

Wide Compatibility with Diverse Observation Scenarios

Well-suited for electronics repair, PCB inspection, industrial-component testing, teaching-research and sample-quality-analysis tasks.

All-in-one Observation, Recording & Measurement

4K digital imaging replaces traditional eyepiece viewing. Captured images and videos can be saved and exported for data comparison, archiving and post-processing.

Differences from Conventional Digital Microscopes

4K ultra-high-definition imaging: Resolution up to 3840 × 2160 delivers abundant fine details. Most ordinary digital microscopes only offer 1080P with limited resolving capability.

Dual-port output: HDMI for real-time on-monitor viewing; USB for PC-software-based measurement. Most competing models feature single-USB-only output and require a host PC for operation.

Offline USB-flash-drive storage: Capture photos and videos directly to USB flash drive without a PC. Conventional digital microscopes require a computer for image saving.

Professional measurement software: Industrial-grade software supports length, angle and area measurement. Basic-grade digital microscopes only support simple snapshot capture without measurement capability.

Rugged industrial stand & base: Rigid mechanical-structure for repeated production-line inspection. General-purpose units adopt lightweight brackets with poor stability.

On-Site Evidence & Reliability (First-hand Testing)

1. 4K Ultra-HD Imaging Accuracy Verification

The complete unit is fully calibrated with a professional resolution test target, delivering native 3840 × 2160 4K ultra-HD output. The high-sensitivity sensor accurately reproduces fine surface textures of color-ring resistors, PCB traces, component pins, solder joints and other electronic features. Consistent sharpness is maintained across the full field-of-view from center to edge without edge blurring.

2. Multi-Function Test for Shooting / Recording / Measurement

Adopting an all-in-one integrated system, it simultaneously supports screenshot capture, video recording and precision dimensional measurement. It yields low repeated-measurement deviation under stable laboratory-conditions and is capable of detecting length, diameter, angle, area and other parameters, fully meeting electronic-component-quality-inspection requirements.

> Shooting: One-click saving of high-definition workpiece images for defective-product archiving and record-keeping.
> Recording: Real-time inspection-video recording to fully document dynamic production-line inspection workflows.
> Measurement: Built-in measurement program enables fast dimensional-verification for electronic components.

3. Stable Hardware and Display Adaptation

Direct HDMI connection to high-definition monitors enables lag-free real-time observation. Equipped with heavy-duty base and lifting stand; the instrument operates stably free of shake during long-duration continuous production-line inspection. The matched dimmable LED ring-light provides uniform supplementary illumination, eliminating reflections and shadows on resistors, circuit boards and other electronic parts.

What Inspections Are Suitable for 21-135 × Magnification?

Electronic Components: PCB boards, FPC flexible cables, resistors, capacitors, IC chips, solder joints and connector terminals. Detect cold-solder defects, oxidation, bent pins, circuit scratches and component damage; capture subtle circuit flaws under 21-135 × magnification with measurement, photo-capture and video-recording functions.

Hardware & Metal-Machined Parts: Drill bits, milling cutters, precision-stamped metal parts and micro-screws. Inspect cutting-edge chipping, micro-surface cracks, burrs, abrasion and machining scratches; identify micron-level metal defects via 4K ultra-HD imaging.

LED & Plastic-Molded Products: LED chips, injection-molded housings, die-cut plastic pieces and silicone buttons. Check surface stains, notches, rough edges, deformation and glue bubbles; ultra-clear 4K output reveals minor cosmetic defects on plastic components.

Mini-Precision Components: Micro-springs, contact terminals and small stamped workpieces. Measure assembly-gap height difference and crimp flatness; perform pixel-level length, pitch and hole-diameter measurement at 21-135 × zoom.

How to Choose a Model

For precision visual-inspection with 4K ultra-HD imagery

It adopts native 4K ultra-HD imaging to restore tiny details such as resistor color-rings, PCB traces, micro-scratches and burrs, well-suited for strict appearance-inspection of electronic components and circuit boards.

For integrated capture, video-recording and measurement workflows

Built-in all-in-one measurement system supports real-time dimensional calculation, one-click photo capture and video recording. Inspection, measurement and file-saving can be completed directly on-monitor without extra software, simplifying QC workflows.

For streamlined factory-workstation deployment with fast monitor-connection

Equipped with HDMI direct output, adjustable stand and thickened stable base. It operates independently with only a monitor and simple wiring, ideal for rapid sampling-inspection on production-lines and daily-maintenance stations.

For universal-inspection covering electronics, PCB and miniature-hardware

Supplied with dimmable ring-LED light with adjustable brightness for flat workpieces including resistors, capacitors, circuit boards and small precision-metal parts. Widely used in electronics-repair, incoming-material QC and laboratory-sample observation.

For QC-image-archiving and quality-traceability requirements

Photos and videos captured during inspection can be saved in batches to record product-defect status, supporting later re-examination, test-report export, factory-QC and outgoing-inspection archiving.

Frequently Asked Questions

Q1: Is regular calibration required for daily operation?

A1: No. The unit is precisely factory-calibrated and maintains stable accuracy under fixed working parameters.

Q2: Images stay blurry and cannot achieve sharp focus, what should I do?

A2: Clean lens dust and oil stains; avoid strong ambient-light interference. Fine-tune working-distance according to workpiece thickness to obtain clear imagery.

Q3: Heavy reflections / glare on metallic samples?

A3: Adjust ring-light brightness and angle to reduce specular reflection. Polarizing accessories can eliminate strong glare spots and enhance visibility of burrs, cracks and surface textures.
