Air SafeCheck

Room air quality monitor / alarm

The Air SafeCheck monitor was specially developed to measure indoor air quality in rooms. It is not to be regarded as a scientific measuring instrument. Its internal sensor is very sensitive to VOCs such as toluene and formaldehyde from wood finishing and building products (furniture and decorations), as well as to other air contaminants released by cigarette smoke, ammonia, hydrogen sulphide, etc. It is also sensitive to odours such as carbon monoxide, alcohol, disinfectants. It is also sensitive to odours such as carbon monoxide, alcohol, disinfectants and other odours. The Air safeCheck monitor is a complete solution that displays ambient temperature, humidity and the concentration of various contaminants.
