CHN SPEC EZ-200 Bench-top Spectrophotometer (360nm-780nm, ΔE*ab≤ 0.03)

The CHN SPEC EZ-200 Bench-top Spectrophotometer is a new-generation, professional bench-top color measurement device developed by CHNSpec. It stands out as an economical and highly efficient solution for businesses requiring a versatile instrument. It combines wide-wavelength spectral analysis capabilities with excellent performance in measuring both surface reflectance and liquid transmittance, all at an optimized investment cost.

Outstanding Technological Features

Wide Spectral Measurement Range from 360nm to 780nm: The EZ-200 features comprehensive spectral data scanning and analysis across a wide wavelength range, covering the entire visible light spectrum and extending into the ultraviolet (UV) region. This capability allows the device to precisely measure the color of various materials while effectively supporting the analysis of samples containing Optical Brightening Agents (OBAs).

Stable and Reliable Repeatability (ΔE*ab ≤ 0.03): The repeatability error between measurements is exceptionally low (less than or equal to 0.03) when tested on a standard white plate. This index ensures stable accuracy, keeping the company’s measurement results consistent across production shifts and minimizing any device-induced deviations.

Integrated Reflection and Transmittance Measurement: The versatile design of the EZ series allows the instrument to flexibly handle any sample state. The device can measure the surface color of opaque materials (plastics, paints, textiles) while also measuring the spectral transmittance, Haze, and Yellowness Index of transparent or liquid samples.

Intuitive Camera Positioning and Flexible Measurement Chamber: The instrument integrates an internal camera system that displays the measurement area directly on the computer screen, enabling operators to achieve absolute alignment accuracy. The top-opening measurement chamber offers spacious room, making it easy to switch between various solid sample holders, powder cells, or liquid cuvettes ranging from small to large sizes.

Durable Xenon and LED Combined Light Source: The combination of a pulsed Xenon lamp and a full-spectrum LED system delivers uniform light energy across the entire wavelength range. This high-durability light source generates no heat, protecting sensitive samples from physical property alterations, and ensures long-lasting performance in industrial environments.
