We always adhere to the concept of “Providing what you need with what I specialize in” to promote the continuous improvement of after-sales service. Moreover, regular on-site maintenance and cleaning work will be carried out for the customer’s measuring instruments and measuring frames. This will extend the service life of equipment, make sure the equipment is always in optimal working condition and guarantee the accuracy of data measurement. For the sudden failure of customer products, we will give remote inspection guidance at the first time and then provide after-sales and on-site maintenance to solve the worries of customers.?
