Selection FAQ

Can the configuration of HV-20 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.
