Witt has launched RLA 100, a low-cost alarm measuring device that measures concentrations of CO2 in ambient air from zero up to 50,000ppm (five per cent) (volume).
The RLA 100 is said to offer protection against the health hazards of this colourless and odourless gas, which is often found and used in the food industry, metalworking and fabrication industries, chemical processing and waste management.
It 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.
If necessary, additional devices can be controlled - for example, extraction units can be started or machinery can be stopped by means of a potential-free contact.
