CHN SPEC EZ-100 Bench-top Spectrophotometer (400nm-780nm, ΔE*ab≤ 0.03)

CHN SPEC EZ-100 Bench-top Spectrophotometer (400nm-780nm, ΔE*ab≤ 0.03)

The CHN SPEC EZ-100 Bench-top Spectrophotometer is the standard professional bench-top color measurement device developed by CHNSpec. It stands out as the most economical solution in the EZ series, specifically designed for businesses requiring a versatile instrument with stable operation that meets the needs of both surface reflectance and liquid transmittance measurements within an industry-standard wavelength range.

Outstanding Technological Features

Standard Spectral Measurement Range from 400nm to 780nm: The EZ-100 scans and analyzes spectral data across the 400nm to 780nm wavelength range. This range covers the entire visible light spectrum detectable by the human eye, enabling the device to accurately identify and analyze the color of most common industrial materials today.

Stable and Reliable Repeatability (ΔE*ab ≤ 0.03): The instrument features an exceptionally low repeatability error between measurements (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 Dual Reflection and Transmittance Modes: The signature versatile design of the EZ series allows the EZ-100 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 precise sample alignment. 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.
