Three Surveillance Laboratory Laboratory Comparisons in Jiangsu

In order to ensure the accuracy and reliability of the laboratory on-site monitoring instrument monitoring results, according to the plan at the beginning of the year, on September 29th, Changshu CDC and Kunshan and Zhangjiagang CDC professionals performed the on-site monitoring equipment at the CDC in Kunshan City. Comparison between laboratory rooms.

The CDCs of Changshu, Kunshan and Zhangjiagang use the same class of sound level meters, thermometers, illuminometers, anemometers, carbon monoxide, carbon dioxide, formaldehyde detectors, dust particle counters, dust samplers, atmospheric samplers, ultraviolet intensity meters, The on-site monitoring instruments such as WBGT index instrument and microcomputer laser dust instrument are continuously monitored three times in the same place and at the same time and by the same monitoring technician in strict accordance with the operating procedures. The original records of the site and the instrument usage records are carefully filled in to calculate relative deviations. Compare with the acceptable error and judge whether the two instruments have consistency. The comparison instrument results show that the difference between the instrument detection data is in the specified interval, and each instrument is in a good working condition. Through the comparison of instruments, the accuracy and consistency of the monitoring data of environmental health testing instruments were verified, thus ensuring the objectivity and accuracy of the test data.

Changshu, Kunshan, and Zhangjiagang Three Disease Control Centers The laboratory intercomparison between on-site monitoring instruments is the first of its kind this year. We will continue this work in the future to ensure the quality control of on-site monitoring instruments.
