About Contract Measurement Services

In the fields of industry and manufacturing, contract measurement services typically refer to the provision of measuring instruments and professional application engineers by service providers, who come to the client's site to develop measurement plans according to the client's established requirements, perform measurements on the targets, and issue professional measurement reports. Additionally, contract measurement services may include equipment rental, equipment maintenance, personnel training, data analysis, and more.

Since industrial-grade/laboratory-grade precision measurement equipment is usually quite expensive, manufacturing enterprises can customize measurement plans on demand by using contract measurement services, thereby avoiding costs related to equipment procurement, personnel training, and professional skill development, thus adding value and efficiency to production.
