The LS372 is a 45ยฐ/0ยฐ portable colorimeter with a 4 mm measuring aperture and a 3.5-inch touchscreen, designed to measure and compare color precisely even in small printed areas (labels, packaging, brochures, etc.). It meets D50 standard lighting conditions, aligning with industry color evaluation practices.
๐งช Key Features
๐ Small-Area Measurement (4 mm Aperture)
The 4 mm aperture enables precise color measurement on small graphic areas such as narrow print swatches, tiny labels, and intricate packaging designs โ reducing edge interference and improving accuracy.
๐ Industry Standard Lighting
Uses D50 standard illumination, which matches standard viewing conditions used in graphic arts and printing for reliable color assessment.
๐ฑ Easy Operation & Smart Display
3.5-inch capacitive IPS touchscreen with intuitive UI makes operation simple without needing many physical buttons.
Language options include English and Chinese.
๐จ Built-In Color Cards & Quick Matching
Includes multiple standard electronic color charts that can match the top 3 closest color codes with high accuracy โ ideal for quick color reference and verification.
๐ง Color Difference & Quality Control
Supports color difference comparison using multiple ฮE formulas (ฮEab, ฮEuv, ฮE94, ฮEcmc, ฮE*00, etc.).
You can set thresholds for pass/fail quality control, helping with batch consistency checks.
๐ฏ Precise Alignment & Stability
Triangular support structure around the measurement hole improves alignment and stability during measurement.
Built-in white calibration board lets you calibrate easily without carrying a separate plate.
๐ Data Management & Connectivity
Stores large amounts of color data locally and supports mobile app and PC software, helping synchronize and manage color databases and generate reports.
๐ Excellent Consistency
Repeatability is ฮE*ab โค 0.03, meaning very stable and repeatable results for quality-critical work.
