Core Design & Structural Advantages

Ergonomic Two-Tone Aesthetic: The white upper shell and black lower base create a clean, clinical appearance, with a smooth, high-gloss finish that is easy to disinfect and resistant to chemical cleaners, critical for medical environments.
Integrated Functional Interface: Precisely positioned large display window, 4-button control cutouts, and side interface ports (for power, data, and sample input) enable seamless integration of screens, circuit boards, sensors, and wiring harnesses, streamlining assembly and reducing production costs.
Reinforced Structural Rigidity: Thickened walls and internal ribbing provide superior impact resistance and load-bearing capacity, protecting sensitive diagnostic components from mechanical shock and vibration during transport and daily use.
Optimized Sample Access: The dedicated sample inlet slot on the top shell is designed for quick, easy insertion of test strips or cartridges, aligning with clinical workflow efficiency.
Medical-Grade Material Performance: Manufactured from biocompatible, non-toxic engineering plastics, compliant with global medical device safety standards, ensuring no leaching or contamination during patient testing.
Customizable Branding & Marking: Supports custom logo embossing, port labeling, and part number marking to meet OEM traceability and brand identity requirements.
