Infrared cartridge options have been added to the multi-gas Lumidor Impact Pro. One of three infrared sensors can be chosen as one of the four sensors that come standard in a four-sensor, multi-gas cartridge. Two infrared sensors monitor for methane and other hydrocarbons and a third sensor option measures for percentage volume of carbon dioxide. The cartridge also includes a sensor that measures for oxygen levels and two sensors for a range of user-selected toxic gases, including carbon monoxide, hydrogen sulfide, chlorine, ammonia, sulfur dioxide and nitrogen dioxide.
