Are the instruments supplied by Machine-Win brand-new and original?

Yes. Machine-Win supplies brand-new, original instruments with factory serial numbers, standard accessories and manufacturer documentation. Before shipment we can share inspection photos or videos of the unit, serial label and packaging so buyers can verify the exact configuration.

Can Machine-Win provide calibration and repair services?

Yes. In addition to instrument sales, Machine-Win offers instrument repair and calibration support. Calibration documentation can be arranged on request, and our engineers help define the required test points and accreditation level before the order is confirmed.

Which countries does Machine-Win ship to?

Machine-Win has delivered to customers in more than 100 countries and regions from offices in Hong Kong, Shenzhen and Nanchang. Standard export documents include a commercial invoice and packing list, and shipments use shock-protected export packing suitable for precision electronics.

Can you source hard-to-find or discontinued test equipment models?

Often, yes. Through a network of over 2,000 qualified suppliers, Machine-Win runs strategic sourcing for specific models, options and spare parts. Share the full model number, required options and quantity so our team can check availability and lead time.

What information should I prepare before contacting Machine-Win?

Prepare the brand and complete model number, required options or licenses, quantity, destination country, preferred delivery terms and any calibration requirements. This allows engineers to confirm compatibility and propose equivalent alternatives if needed.
