5. Suffix Code Definition (Key for Model Selection)

1. VN: Factory-calibrated with nitrogen (N₂), temperature drift ±7%, high versatility, ideal for air and nitrogen measurement
2. VC: Factory-calibrated for carbon dioxide (CO₂), dedicated to CO₂ measurement; temperature drift tolerance widened to ±10%. Fixed offset exists when measuring air/N₂, which requires software correction
3. VA: Argon-calibrated (not included in these three models)

6. Quick Selection Guide

1. Low flow nitrogen/air measurement → AWM5101VN (0~5 SLPM)
2. Dedicated carbon dioxide gas measurement → AWM5103VC (0~15 SLPM)
