Testing Built Around Real Product Performance
BG combines an independent quality-control process with application-focused verification. Our NOXIA calibration system includes 32 testing stations and supports controlled NO and O₂ concentration testing for sensor calibration and performance verification.

Quality-Control Philosophy
Each product category follows a defined inspection and verification process based on its function and application, from incoming material to final outgoing inspection.
Product Development Verification
New references undergo electrical, functional and application-related verification before entering serial production.
Incoming Material Inspection
Sampling and dimensional checks on incoming components — sensor elements, connectors, housings, PCBs and pump parts.
In-Process Inspection
Line-side visual, dimensional and functional checks throughout assembly and calibration.
Functional Testing
Signal integrity, sensor response, dosing accuracy and pump performance verification per product family.
Environmental Testing
High-temperature, humidity and thermal shock testing to verify performance across service conditions.
Testing Capabilities
- NOXIA NOx calibration bench (32 stations)
- Oscilloscope
- Microscope

- Electrical and signal testing
Batch traceability, claim analysis and continuous improvement are integrated into our standard workflow. We avoid absolute claims — inspection and verification are defined per product family, based on its function and intended application.
