Specifications per ESAMBER datasheet V2.5. Subject to change without notice.

Enters the oven with the PCB to synchronously measure temperature, oxygen and vibration, recording in-oven O₂ concentration, temperature and rail vibration as curves. Used for defect analysis (oxidation, bridging, shift, dropped parts), atmosphere-control process optimization, nitrogen-flow regulation to cut cost, and data traceability.

Application areas

• Defect analysis (oxidation / bridging / shift / drop)
• Atmosphere-control optimization
• Nitrogen flow & cost reduction
• Process data traceability
• Reflow oven O₂ validation
