WatchGas PDM+ Oxygen Concentration Meter
It is a small and lightweight gas detector capable of measuring the oxygen concentration in the air. The sensor and battery life are very long-lasting, approximately 2 years.
The PDM+ oxygen concentration meter is a gas detector capable of detecting oxygen in the environment. When powered on, it continuously measures oxygen levels and alerts you with an LED, vibration, and sound alarm when dangerous conditions arise. It is easy to operate, and there is a metal clip on the back of the unit that allows it to be secured to a shirt, belt, helmet, or other items.
