How long is the lifespan of a portable gas detector?

The lifespan of a portable gas detector depends on the model, sensor type, and operating environment. Generally:

Oxygen/combustible gas sensors have a lifespan of approximately 2–3 years.

Electrochemical sensors (CO/H2S, etc.) have a lifespan of approximately 1–2 years.

Battery lifespan is typically 12–36 months. Regular calibration and maintenance can extend lifespan and ensure detection accuracy.
