City Technology has introduced the 4CM, a carbon monoxide sensor designed for challenging environments. Developed to meet stringent toxic gas and mining standards, the unit performs in temperature and humidity extremes, responding to CO hazards and recovering in more than half the time of the industry average. Carbon monoxide exposure to concentrations as low as 100 ppm can be dangerous, and higher levels of exposure can be life threatening. In industry, the gas is routinely found in mining facilities, oil and gas plants, petrochemical facilities, steel plants and wastewater treatment plants. It is also major potential hazard when personnel are required to enter confined spaces.
