It features 4 sensors including Oxygen, Hydrogen Sulfide, Carbon Monoxide and combustible gases. Other sensors available include a lead free Oxygen sensors, a low powered infrared methane sensor, sulfur dioxide and hydrogen cyanide. The detector is packaged in a robust housing with no moving parts. Its battery power offers 2 work shifts of run time for a standard 4 gas meter and up to one week when using a low power infrared sensors. The simple 2 button operation results in ultimate ease of use and significantly reduced time spent training the user.
