Recently, Henan University (hereinafter referred to as the client) purchased a high-performance open tube furnace, rotary pendulum furnace, and vacuum tube furnace from our company for material synthesis and heat treatment in its scientific research experimental projects. After the equipment was put into use for a period of time, the customer encountered some operational and technical problems in daily use, so they applied for after-sales service support from our company.

The customer provided feedback through our after-sales service center via phone that the equipment encountered abnormal OTF temperature display during use. In response to the customer's reported lack of proficiency in operation, the engineer promptly repaired and replaced the instruments, and conducted detailed debugging of the entire system to ensure that all functions of the equipment were restored to normal

The after-sales case of Henan University's tube furnace fully demonstrates our company's rapid response, professional skills, and customer care in after-sales service. Through effective remote support and on-site services, we have successfully solved customer equipment failures, improved user operation skills, and ensured the smooth progress of scientific research work.
