Selection FAQ

Can the configuration of 2205A be adapted to my application?

Yes. Beyond the standard configuration, measuring range, fixtures, optics and software functions can be adapted. Send your sample and test requirements and our engineers will return a configuration list and quotation.

Can I test my samples before ordering?

Yes. Samples can be mailed to our Shanghai Fengxian laboratory for free testing with a written report, or you can book an on-site demonstration to confirm the workflow and data format.

How are lead time, installation and after-sales service handled?

Standard configurations usually ship within 15-30 working days, including first installation, commissioning and operator training. The instrument carries a one-year warranty and software upgrades are free for life.
