CHN SPEC EZ-300 Bench-top Spectrophotometer (360nm-780nm, \u0394E*ab \u22640.02)<\/strong><\/h2>\n

The CHN SPEC EZ-300 Bench-top Spectrophotometer<\/strong> is a new-generation professional bench-top color measurement instrument developed by CHNSpec. Featuring a wide wavelength range and ultra-precise repeatability, this device provides a comprehensive color analysis solution for both reflective samples (solid surfaces, powders, granules) and transmissive samples (liquids, thin films) in laboratories and quality control (QC) departments.<\/p>\n

\"\"<\/a><\/p>\n

Outstanding Technological Features<\/strong><\/h2>\n

Comprehensive Spectral Range from 360nm to 780nm:<\/strong> The EZ-300 possesses the capability to scan and analyze spectral data across an ultra-wide wavelength range, covering the entire visible light spectrum and extending into part of the ultraviolet (UV) region. This enables the instrument to accurately measure the color of all types of materials while effectively analyzing samples containing Optical Brightening Agents (OBAs).<\/p>\n

Ultra-Stable Repeatability (\u0394E*ab \u2264 0.02):<\/strong> The repeatability error between measurements reaches an extremely low level (\u2264 0.02) when tested on a standard white plate. This index confirms the absolute reliability and consistency of the hardware system, helping businesses completely eliminate instrument-induced errors across different production shifts.<\/p>\n

Integrated Reflection and Transmittance Measurement:<\/strong> The versatile design allows the EZ-300 to handle all sample geometries. The instrument can measure the surface color of opaque materials (plastics, paints, fabrics), as well as spectral transmittance, Haze, and Yellowness Index of transparent samples or liquids.<\/p>\n

Camera Positioning and Flexible Measurement Chamber:<\/strong> The instrument integrates a high-definition camera system that displays the measurement area directly on the screen, ensuring absolute alignment for the operator. The measurement chamber is designed with an open-top and ample space, making it easy to switch between various solid sample holders, powder cells, or liquid cuvettes ranging from small to large sizes.<\/p>\n

Superior Combined Xenon and LED Light Source:<\/strong> Utilizing a combination of a long-life Pulse Xenon lamp and a wide-spectrum LED. This system provides uniform light energy across the entire wavelength range, generates no heat to alter the physical properties of the sample, and ensures durable operation for many years without requiring lamp replacement.<\/p>\n
