[China Instrument Network Instrument R&D] A few days ago, the AQSIQ's science and technology project “Ultraviolet Radiation Illumination Calibration Deviceâ€, which was undertaken by the Metrology Institute of Fujian Province, passed the acceptance test. This project has reached the leading domestic level in technology and effectively filled the domestic gap.
According to reports, the device can be calibrated and calibrated UV radiation illuminance meter and other ultraviolet radiation measurement instrument, the measurement range includes UVA1 (320nm ~ 390nm), UVC (253.7nm), measurement uncertainty Urel = (8.1 ~ 8.3)% (k =1). In December 2012, the device passed the expert assessment organized by the General Administration of Quality Supervision, Inspection and Quarantine, and obtained social public measurement standard certificates and assessment certificates.
Ultraviolet radiation technology is widely used in medical and health, optoelectronics, meteorology, aerospace, and industrial and agricultural production and other fields. Accurate measurement of radiation irradiance in the ultraviolet band is of great significance for science and technology and economic development, health care and safety protection.
At present, China's UV irradiance work standards are mainly composed of a spectroradiometer, a standard ultraviolet irradiance meter, and various ultraviolet light sources, which are used to store and reproduce the ultraviolet radiation metrics. Ultraviolet radiation illuminance working reference device is the highest standard for traceability of UV radiation measurements in China. With the introduction of foreign instruments of this kind gradually increased, the calibration of ultraviolet irradiation instruments has emerged the situation of coexistence of multinational standards, thus causing confusion to the majority of users of ultraviolet radiation illumination meters.
During the inspection and acceptance process, the group of experts reviewed and accepted the materials, listened to work summaries and research reports, and viewed the prototype demonstrations on site. They discussed and inquired, and agreed that the research results of this project have greatly improved the UV irradiance calibration results. The accuracy and efficiency of the work can effectively improve the ability and level of detection of ultraviolet radiation in China, improve the evaluation method of ultraviolet irradiation, and have originality and breakthrough in the measurement method of ultraviolet irradiation, filling the domestic gap. The technical level reaches the leading domestic level, and the social and economic benefits are significant. At the same time, it is recommended to increase the promotion and application of the research results.
