This enables detection of dust concentrations down to g/dscf (or mg/m3), roughly 20 times more sensitive than the best opacity detectors. It can also detect much smaller particles, down to less than micron in size. And it has a faster response time of less than 1 sec from detection to output. This provides the ability to monitor and establish baselnes when the particulate is ...
