Laboratory service and support includes a wide variety of services that aim to maintain, restore or improve the functionality of industrial laboratories. Instrument repair is only one aspect of this complicated business area. This category involves out-of-warranty systems or parts not covered under a service contract. Preventative maintenance, calibration, validation, remote support, training, asset management and various types of consulting are other areas where vendors can provide additional service and added value to their product offerings. As a result, the service business has become the main driver of increased revenues for some companies in the instrumentation industry.
