Huicolor CL320 UV Meter

Huicolor CL320 UV Meter

The Huicolor CL320 UV meter is an advanced handheld optical instrument, specifically designed to measure and analyze the intensity and wavelength of ultraviolet (UV) radiation. Equipped with modern spectrophotometric sensor technology, this device provides precise inspection and quality control solutions for industrial UV applications, ranging from UV curing of printing inks and adhesives to sterilization and UV-resistant material testing.

Design and Technology Overview

The Huicolor CL320 features an extremely compact, robust, ergonomic handheld design, optimized for portability and direct measurements on the factory floor or out in the field. The device comes equipped with a sharp color touchscreen that intuitively displays UV spectral charts and technical data in real time.

The outstanding advantage of this series is its intelligent sensor probe, which is capable of withstanding high thermal loads and intense radiation levels, ensuring long-term durability and absolute accuracy over extended periods of use.

Key Features & Benefits

The device integrates core UV spectral measurement technologies:

• Multi-Band UV Measurement: Allows simultaneous measurement or detailed isolation of different UV wavebands, including UVA (excitation, adhesive curing), UVB (medical treatment, weathering testing), and UVC (disinfection, sterilization).
• Comprehensive Spectral Analysis: Beyond measuring total intensity, the meter displays spectral energy distribution charts down to specific wavelengths (nm), enabling users to verify if the UV source emits the exact desired waveband.
• UV Energy Accumulation Measurement: The integrated measurement function calculates the total cumulative UV energy exposed per unit area (mJ/cm² or J/cm²) over a specific timeframe—a critical metric in industrial curing lines.
• Large Memory and PC Connectivity: Stores thousands of measurement data points directly on the device. Supports a USB connection port to export data to specialized software for in-depth analysis and quality report generation.
