The LS155 Color Haze Meter is a lab-grade optical instrument used to measure how transparent or colored a material is. It’s commonly used in quality control for materials like plastics, glass, films, liquids and more to quantify optical properties that the human eye can’t reliably judge.
🔍 Key Features
✔ Multi-parameter optical measurement
It can measure haze, light transmittance, color (CIE Lab, LCh, Yxy), clarity, turbidity, and even Pt-Co (platinum-cobalt) color for liquids — plus it can display the spectral transmittance curve.
✔ Meets Industry Standards
Supports ASTM D1003 and ISO 13468, so the results are compliant with widely accepted international testing methods.
✔ Dual Aperture Design
Includes 5 mm and 14 mm apertures, letting you test both small and larger samples accurately.
✔ Smart, Easy Operation
7-inch capacitive touch screen with a human-machine interface. You can do simple or comparative tests and set tolerance limits.
✔ PC Connectivity
Connects via USB (Type-C) and comes with software for data export, reporting, and analysis.
✔ Designed for Accuracy & Stability
It uses a full-spectrum LED light source and a spectral sensor with fitting algorithms, rather than traditional silicon detectors, leading to better precision and repeatability.
✔ Robust Build
Core optical parts are made with aviation-grade aluminum and CNC machining, giving micron-level alignment and better long-term stability.
✔ Ambient Light Filtering
Unique signal processing ensures that external ambient light doesn’t mess with the results.
