Why won't my Inficon Security Sensors detect CO2?
- MMichael CruzAug 14, 2025
If your Inficon Security Sensors unit isn't detecting CO2, several factors could be at play. First, ensure the unit has completed its warm-up phase, indicated by a beeping sound and the absence of flashing yellow lights (a single green light flashing is acceptable). If yellow lights are scrolling, allow 90 seconds for warm-up. If the issue persists, contact INFICON. The pump's functionality is also crucial; listen for it near your ear after warm-up, verifying it's not a low battery issue. A clogged filter cartridge can impede airflow to the IR cell, so replace it with a new one. Finally, a dead battery can prevent detection, so please refer to section #3.
