Quality Control Process
1
Raw Material Inspection
All incoming materials — ceramic elements, wire harnesses, connectors — are inspected against specifications before entering production.
2
Precision Assembly
Automated assembly lines with laser welding ensure consistent build quality. Each unit is assembled under controlled cleanroom conditions.
3
Gas Sensitivity Testing
Every sensor is tested with calibrated NOx gas concentrations to verify accurate readings across the full operating range.
4
Temperature & Vibration Testing
Random samples undergo extreme temperature cycling (-40°C to +125°C) and vibration stress tests to simulate real-world conditions.
5
Final QC & Packaging
100% of units pass a final electrical and functional test before packaging. Custom packaging and labeling available for OEM/ODM clients.
Global Market Presence
We export to over 50 countries across North America, Europe, South America, the Middle East, Southeast Asia, and Africa. Our logistics partners include DHL, FedEx, UPS, and major freight forwarders for sea and air shipments.
