New CO2 warning device introduced from Witt


Witt has launched its ‘RLA 100’ warning device, a new and low-cost alarm device to measure concentrations of carbon dioxide (CO2) in ambient air from 0-50,000 ppm (5%) (Volume).

The system 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. If the adjustable CO2 alarm limit is exceeded, the device gives an audible and visual alarm. Also, if necessary, additional devices can be controlled – extraction units can be started or machinery can be stopped by means of a potential-free contact for example.

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.
