Using an oxygen meter is essential for determining if a tank has been successfully inerted because the primary goal of inerting is to reduce the oxygen level within the tank to prevent potential flammable atmospheres. An inerted tank should have an oxygen concentration below a certain threshold, typically around 10%, which ensures that combustion cannot occur.

The oxygen meter measures the percentage of oxygen present in the air inside the tank. If the reading is significantly low, it indicates that the inerting process has been successful, and the environment is safe from combustion risks. This is why this type of meter is specifically designed and utilized for safety checks in environments where flammable vapors may be released.

While other meters also have their functional purposes — the flammable vapor meter detects the presence of flammable vapors, the pressure gauge monitors internal tank pressure, and the temperature gauge assesses temperature changes — they do not provide the specific information needed to confirm the successful reduction of oxygen levels, which is critical for safety in tank inerting operations.
