Overview
Emissions and Stack LS155 High-Precision Liquid Colorimeter with Touchscreen Display is a multifunctional haze meter built for the precise measurement of color, transmittance, haze, turbidity, and platinum-cobalt (Hazen) value in film, plastic, packaging, pharmaceutical liquids, and glass. Featuring D/0° illumination geometry, full-spectrum LED, 5 mm and 14 mm apertures, and a 7-inch capacitive touchscreen, it offers spectral transmittance curve visualization, robust repeatability (ΔE*ab ≤ 0.03), and compliance with both ASTM and ISO testing standards. The benchtop unit supports USB data export, PC software, and delivers both horizontal and vertical measurement modes—complete with a 1-year warranty, free technical support, and OEM customization.
