GasDoc DS-100 How to Test if the Carbon Monoxide Detector is Working: Carbon monoxide is a colorless odorless toxic gas produced when carbon-based materials are not completely burned. Here are two recommended safe testing methods: 1.Using a Lit Cigarette: Light a cigarette and place the DS-100 detector near the smoke. 2.Burning organic matter in a low-oxygen environment: Light a piece of paper then extinguish the flame allowing it to smolder (produce smoke without flames) . Place the smoldering paper and DS-100 inside a sealed non-flammable container (like a glass jar) to test with the smoke. If the device displays a reading or triggers an alarm it is working properly. Note: Avoid testing with car exhaust or gas stoves as it’s difficult to accumulate enough CO in open or well-ventilated areas. 3-in-1 Measurement: The DS-100 is a portable detector that
