After-Sale Service
Installation & On-Site Training
Our professional service engineers will install and commission the equipment, then train your personnel until they can operate, maintain, and troubleshoot independently. Training covers operation, maintenance, fault prevention, and is completely free. One-stop perfect service is guaranteed.

Warranty & Lifetime Maintenance
The equipment has a one-year warranty from qualified installation. During this period, non-human fault parts are replaced free (excluding normal consumables). After warranty, we provide lifelong maintenance, charging only cost price for spare parts. This ensures affordable long-term support.

Rapid Fault Response
We respond to all fault reports within one hour. For unresolved issues, engineers arrive on-site within 24 hours for out-of-province customers. Warranty repairs (parts, travel, labor) are free for instrument-caused failures. 24/7 hotline: 18390982517

Customer File & Active Reminder
We maintain detailed computer files for every customer, recording equipment history and consumable life. Our system proactively reminds you of scheduled maintenance, troubleshooting, and consumable replacement. Regular return visits and usage surveys are conducted to ensure optimal performance.

Preventive Maintenance Service
Our unique “preventive maintenance” approach provides free lifetime door-to-door equipment checks, regardless of warranty status. We regularly maintain your system to prevent failures before they occur, rather than waiting for breakdowns. This extends equipment life and reduces unexpected downtime.

Free Technical Support
Headquarters has dedicated technical support engineers who promptly answer all your technical questions, ensuring long-term cooperation. Free personnel training includes installation, debugging, operation, maintenance, and troubleshooting. Training is face-to-face at your site or centrally, with 1-3 trainees per set, all at no cost.
