How to Order
From Inquiry to Installation in 4 Steps
- 01
Confirm the method
Choose the model by sample type, standard, range, throughput and acceptance criteria.
- 02
Prequalify the supplier
Request the factory, certificate, CRM, application and export evidence relevant to your tender — or, for partners, pass training and approval first.
- 03
Compare the RFQ
Confirm voltage, scope, delivery, payment, warranty and spare-parts terms in writing.
- 04
Accept and support
Agree the factory/site acceptance record, training scope and post-delivery contact before payment.
Guides
