I  Product Overview

     The CL320 UV meter is a UV detection equipment independently developed by HUICOLOR Company. The instrument adopts UVA, UVB, UVC filters and CMOS detectors as optical acquisition components, which can synchronously collect the radiation power of ultraviolet UVA, UVB, and UVC. The instrument only has one measuring aperture, which can synchronously test the radiation power of UVA/UVB/UVC, with high integration and more scientific and convenient use

     The instrument is equipped with a 1.14-inch TFT color screen, 800mAh lithium-ion battery, Bluetooth/WIFI multifunctional chip, and large capacity storage.

     The instrument has manual mode, continuous mode, and automatic measurement modes, with simple operation and easy portability.

     The instrument is widely used in automated detection of UVA, UVB, and UVC ultraviolet radiation power, with high cost-effectiveness.

II  Product Characteristics

     1. The instrument uses UVA, UVB, and UVC filters and CMOS detectors as optical acquisition components. Through one Φ 10mm measuring aperture, the radiation power of UVA, UVB, and UVC can be synchronously collected, making the UV power distribution at the same position more accurate and clear. The spectral response of the detector is shown in Figure 2.

      The instrument supports user calibration and can adjust the proportion coefficient of UVA/UVB/UVC, making it easy to operate.

III  Applications

     3.1 UV radiation power detection of UV ink in the printing industry

      When using UV ink for printing in the printing industry, it is usually necessary to control the radiation power of the UV light source. The CL320UV energy meter can easily measure the irradiance power of UVA/UVB/UVC.

      The user turns on the CL320, selects automatic mode or continuous mode, places the measuring aperture facing upwards (the aperture is aligned with the direction of UV lamp irradiation) on the conveyor belt, and the instrument automatically detects the irradiance power of the UV lamp.

      If users need to monitor the UVA/UVB/UVC irradiance of ultraviolet light sources in real time, they can fix the compact CL320 and collect the UVA/UVB/UVC irradiance in real time through a PC computer, thereby achieving the requirement of real-time monitoring of ultraviolet light source irradiance.

     3.2 Outdoor sunlight UV energy detection

      Most of the UVB and UVC in sunlight are absorbed by the air, but a portion of UVA can penetrate through the air and reach the ground. Users can use CL320 to measure the ultraviolet intensity of sunlight reaching the ground, and the instrument has a wide range of applications in the photovoltaic industry and skin care.
