For detecting trapped gases in hazardous applications, Impact Pro assists safety engineers at sites and confined-space rescue incidents where carbon monoxide, low oxygen levels, and other gases may be present. Sensors are built directly into cartridge, and up to 4 gases - carbon monoxide, oxygen, hydrogen sulfide, flammable - may be detected simultaneously. IP67-rated detector offers one-touch operation and multilingual display as well as Safelink communications option.
