✨ Key Features
✔ Easy to Use
The meter can be put on the surface and measured immediately with no button press required in basic mode.
✔ Normal & QC Mode
Normal Mode for single measurements.
QC Mode allows setting upper & lower limits for automatic qualification results — ideal for batch inspections/quality control.
✔ Accurate & Stable
Uses D65 light source and photopic spectral response to improve accuracy on colored samples.
High repeatability/resolution for consistent results.
✔ Robust Design
Passes extensive quality tests (thousands of calibration, stability, vibration and aging tests) to ensure reliability.
✔ Ergonomic & Portable
Lightweight ergonomics with a comfortable grip.
✔ Long Battery Life
Auto-shutdown and efficient power use for extended measurement sessions.
📜 Standards & Compliance
