NEW GAS WARNING DEVICE FOR CO2 FROM WITT

Witt, the gas safety, control, mixing and analysis equipment supplier has launched ‘RLA 100’ a new, low cost alarm measuring device to measure concentrations of carbon dioxide (CO2) in ambient air from 0 up to 50,000ppm (5%) (Volume). It offers protection against the health hazards of this colourless and odourless gas, often found and used in the food industry, metalworking and fabrication industries, chemical processing and waste management. The “RLA 100” is supplied as two components with the compact gas detector being placed within the hazard area and the signalling unit located outside. Basically, if the adjustable CO2 alarm limit is exceeded, the device gives an audible and visual alarm. If necessary, additional devices can be controlled, e.g. extraction units can be started or machinery can be stopped by means of a potential-free contact. Even small amounts of carbon dioxide can have an influence on human organisms; a concentration of 0.3% in ambient air can be harmful to health. A ratio of 5% can cause headaches and dizziness and 8% or more can lead to unconsciousness or even death.
