With practical actions, they showed the loyalty to the motherland and the quality cause once again!
Rail Transit
Carry Out Calibration of Temperature Measuring Instruments to Ensure Effective Prevention and Control of Public Transportation
Crowded area such as railway station, metro station is undoubtedly citizens try to stay away from during the pandemic period, but the staff of GRG Test chose to charge ahead and fight side by side with the frontline prevention and control staff of rail transit to jointly build up a "pandemic prevention protection screen" for public safety. During the Spring Festival, under the unified deployment of the metrology departments of People's Government of Guangdong Province and Guangzhou Administration for Market Regulation, the GRG Test technical team voluntarily gave up the Spring Festival holiday and rallied to carry out calibration services for infrared thermometers and other equipment at several Guangzhou metro stations such as Nansha Passenger Port Station, Airport South Station, Airport North Station and Tianhe Passenger Station. During January 24-29, the team worked overtime to ensure the first batch of infrared thermometer inspection tasks and temporary increasing tasks of Guangzhou Metro, completed the on-site calibration tasks for a total of 16 stations and 108 infrared thermometers. Besides, from February 1, Guangzhou Metrology Laboratory arranged personnel to work overtime to ensure the calibration of the second batch of infrared thermometer sent by Guangzhou Metro. By ensuring the accuracy of temperature measuring equipment, the prevention and control system of Guangzhou's largest public transportation network can be effectively operated.

On January 24 (New Year's Eve), Long Yang, secretary of the metrology comprehensive party branch and deputy chief engineer of the metrology center, led the technical team to carry out on-site calibration of infrared thermometers in the metro station.


Working Overtime to Guarantee the Calibration of Infrared Thermometer
Li Xin, director of the thermal physics and chemistry laboratory, is the backbone of the Guangzhou Metro Calibration Project. She is also a party member with 13 years of party standing. Since the Chinese New Year's Eve, she has been traveling back and forth between the company and various metro stations, participated in the calibration of infrared temperature measuring instruments in the metro. From participating in the formulation of the service guarantee scheme, to coordinating human and material resources, to going to the designated site to carry out calibration services, to the laboratory calibration of instruments sent by customers in the later stage, Li Xin hardly had a rest during the Spring Festival. Talking about the feeling of this support task, she frankly admitted that when performing the calibration the first batch of infrared thermometers on-site, she felt that the pressure was relatively large, the time was tight, and the task was heavy. It was a double test for the professional skills and physical quality of the technical team. Finally, the task was successfully completed under the team's concerted efforts. "These are what I should do, and Party members should be in the front. Compared with the medical staff who go deep into the front line of the pandemic area, what we did is only a small part," Li Xin said.
Medical Treatment
Carry out Calibration of Medical Equipment to Support Medical Research and Prevention & Treatment
Since the outbreak of COVID-19, the GRG Test has played its advantage of technical service in the field of measurement and calibration, actively responded to the needs of many medical institutions throughout the country, assisted them to smoothly carry out medical research and prevention and control by providing measurement and calibration services. During February 3-4, Wuxi Measurement Laboratory of GRG Test successively supported the measurement and calibration tasks of Affiliated Hospital of Xuzhou Medical University and Xuzhou Mining Group General Hospital, the designated hospitals for pandemic prevention and control in Jiangsu Province, provided on-site calibration for biosafety cabinets used for pandemic prevention and control research, so as to ensure the smooth development of the prevention and control work. During the period, GRG Test gave full play to the advantages of the national integrated service network. The market personnel and laboratory technicians in East China cooperated to quickly formulate a technical service guarantee scheme, coordinated the allocation of overtime technicians and standard equipment, and rushed to the hospital on the premise of ensuring the safety of employees. The measurement work was completed with high efficiency and high level, which was highly praised by the medical workers. The technical team will also go to the Changxing County People's Hospital in Huzhou City, Zhejiang Province to carry out on-site measurement for the biosafety cabinets, ultraviolet lamps, negative pressure rooms and other equipment in PCR laboratories, emergency testing rooms, testing specimen rooms and heating testing rooms.

In this support task, the "post-90s generation" became the backbone of the technical support team. "Sense of urgency" is the first feeling came to Zhang Lei, director of thermal physics and chemistry laboratory of the Wuxi measurement laboratory. As a communist, as well as the on-site technical director of the task, he should efficiently and orderly cooperate with the hospital to complete the task while ensuring the safety of team members. "My family was worried learning that I'm going to the hospital, but someone has to step forward" Zhang Lei said with a smile, "party members should set a good example for everyone. I just did what many people would do."
During the special period when all places are strictly preventing the pandemic, overall planning and coordination are also facing many challenges. Sun Jie, the deputy director of Wuxi Measurement Laboratory, has a deep understanding of this. In order to complete calibration tasks with high efficiency and quality, on the one hand, it is necessary to arrange nearby thermal physics and chemical professionals to return to Wuxi in advance for standby; on the other hand, under the condition of the closure of high-speed road and park, the drivers and vehicles should be coordinated to retrieve the borrowed biosafety cabinet calibration device from Hangzhou testing base in time. During this period, it is also needed to communicate with the hospital about safety protection measures and strictly protect the safety of on-site technicians...The preparations for each link need to be done well to complete the task with high quality and live up to the trust.
