A Guangzhou Co., Ltd. came to our company for consultation on flat panel detectors. The customer consulted the public security and military agencies. The number was about 80. The customer wanted to come to interview, but the customer did not know the specific parameters. It was connected with another customer, so If the customer wants to come, we don’t know how to prepare. First of all, we declined the customer, but the customer indicated that he still wanted to come. The customer said that he wanted to see the quality and cost-effectiveness of the flat panel detector. After agreeing to the customer, there was no reply.
