Profile: PPM Technology Ltd. manufactures portable & fixed gas detection instruments for formaldehyde and other toxic gases in any indoor environment. We have developed a range of toxic gas instrumentation based on an unique electro-chemical sensor, which we now manufacture ourselves, for the detection of airborne formaldehyde and glutaraldehyde. This range is soon to be supplemented by a range of instruments for other common gases monitored in constructing an IAQ profile for building management and similar situations. Our IAQ profile system has been designed to give a visual representation of indoor air quality in buildings, as part of the buildings management standards in relation to conditions such as "sick building syndrome".
