CHOTEST, a National-Level "Little Giant" Enterprise specializing in precision metrology instruments in China, has built its reputation not only on competitive pricing but, more importantly, on fully in-house hardware and software development, advanced multi-sensor integration, and exceptional large-scale customization capabilities.

Compared with leading international brands such as Hexagon and Keyence, CHOTEST's competitive advantages are reflected in the following key technical strengths:

1. Fully In-House Hardware & Software Development with Advanced Sub-Pixel Algorithms

CHOTEST has a dedicated R&D team of several hundred engineers. Its measurement software, including the Vision Measurement Management System, and all core algorithms are developed entirely in-house.

Superior Edge Detection for Challenging Features

The proprietary sub-pixel image processing algorithms excel at measuring difficult industrial features such as:

• Burrs
• Chamfers
• Transparent materials
• Highly reflective surfaces
• Weak or low-contrast edges

Advanced edge extraction and multi-segment curve fitting deliver excellent repeatability comparable to leading international brands while significantly reducing operator-dependent measurement variation.

2. Advanced Multi-Sensor Fusion Technology (2.5D / 3D Measurement)

CHOTEST's expertise originates from nanometre-level laser metrology, making multi-sensor integration one of its core strengths.

Unlike conventional vision systems that simply "see" parts, CHOTEST seamlessly integrates:

• Optical vision measurement
• Touch probes
• White-light confocal sensors
• Chromatic confocal sensors
• Laser displacement sensors

All sensors operate within a unified coordinate system, allowing optical measurements, height inspection and laser profile scanning to be completed within a single measurement program.

The result is:

• Faster inspection
• Consistent coordinate alignment
• Unified data management
• High-speed hardware response

3. Exceptional Large-Range Measurement and Customisation Capability

Many international vision systems are designed primarily for relatively small measuring ranges.

CHOTEST offers highly flexible custom solutions supported by its expertise in precision granite machine structures and heavy-duty motion control systems.

Large-format automatic vision measuring machines can be supplied with measuring ranges exceeding:

• 920 mm × 840 mm
• or fully customised dimensions for specific applications.

These systems are particularly suitable for:

• Large PCB inspection
• LCD panels
• Automotive stampings
• Large precision components
• Batch array measurements

4. Excellent Stability for Shop-Floor Environments

CHOTEST machines feature high-rigidity granite bridge structures that provide excellent:

• Mechanical rigidity
• Vibration resistance
• Thermal stability

Unlike many imported high-end systems that require controlled laboratory conditions (typically 20 ±1°C), CHOTEST's CHT and Novator series are designed to perform reliably directly on the production floor.

Their optimised anti-interference design minimises the effects of:

• Temperature fluctuations
• Machine vibration
• Factory environmental disturbances

making them ideal for high-frequency in-process inspection.

5. Localised Software Customisation and Rapid Technical Support

CHOTEST software can be tailored to individual manufacturing workflows, including:

• Custom inspection reports
• Label printing
• Automatic data upload to MES systems
• SPC quality control integration
• One-click export of customised inspection reports

Because both the hardware and software are developed in-house, application modifications and special measurement routines can be implemented quickly.

Compared with many imported systems—where software upgrades, algorithm changes or custom applications often involve long lead times and high engineering costs—CHOTEST engineers can rapidly develop customised measurement macros and application solutions directly for specific customer parts.

Summary

CHOTEST combines metrology-laboratory precision with the robustness and flexibility required for modern manufacturing environments.

Rather than simply being a vision measuring machine, it is a highly expandable metrology platform capable of integrating multiple sensing technologies while maintaining exceptional stability, productivity and adaptability for shop-floor inspection.

Whether your challenge is improving measurement accuracy, increasing inspection throughput, or measuring difficult materials such as transparent or highly reflective components, CHOTEST provides a versatile solution designed to meet demanding industrial applications.
