The BGD 552 Series Spectral Colorimeter is the latest generation of high-precision colorimeter developed by Biuged. It adopts a dual-optical-path design, which monitors light source energy fluctuations while measuring sample signals, reducing interference and achieving higher measurement stability. The repeatability index is improved to ΔE*ab ≤ 0.03, ensuring high standards in measurement speed, accuracy, stability, and inter-instrument consistency.

Additionally, this instrument utilizes an innovative nano-integrated optical component with a thickness of only 5 micrometers as the spectroscopic device, achieving nanometer-level spectral resolution, significantly enhancing color measurement precision. 

Features:

◆ Ultra-High Repeatability (ΔE*ab ≤ 0.03) & Outstanding Inter-Instrument Consistency (ΔE*ab ≤ 0.3) – Certified Grade 1 Metrology

Repeatability is a critical performance indicator for color difference meters. The BGD 552 employs an advanced optoelectronic testing system and undergoes rigorous calibration to achieve unmatched repeatability. Furthermore, it uses BCRA standard ceramic tiles for color calibration and traceability, combined with superior craftsmanship, ensuring exceptional inter-instrument consistency.

 ◆ Powerful & Convenient Calibration Function

The BGD 552 requires no frequent manual calibration. Simply place it on the calibration base, and the instrument will automatically adjust based on environmental conditions, ensuring optimal performance at all times.

The calibration base features a zirconia (ZrO₂) white tile (Mohs hardness 9, comparable to diamond), which is highly resistant to scratches and unaffected by temperature/humidity changes. Compared to competitors using standard ceramic or plastic tiles, this ensures superior long-term stability and durability.

◆ Multiple Measurement Parameters – Meeting Diverse Industry Standards

     40+ light sources (A, B, C, D50, D55, D65, etc.)

     30+ measurement indices, including：Spectral reflectance，CIE-Lab, CIE-LCh，ΔE*ab，Hiding power，whiteness，yellowness，etc.

◆ Versatile Measurement Adaptability

The BGD 552/2 supports 6 measurement apertures for different sample sizes:

Stable Type：Φ11mm + Φ6mm + Φ3mm

Dexterous Type：▽11mm + ▽6mm + ▽3mm

◆ Built-in HD Camera for Precise Positioning (BGD 552/2 Only)

The BGD 552/2 features a high-definition camera to visually confirm the measurement area, preventing errors caused by misalignment.
