Environmental Monitoring

DUCT-M is a multi-parameter duct-mounted ambient air quality monitor. Its housing is made of corrosion-resistant aerospace aluminum with an IP65 protection rating, enabling stable operation even in outdoor environments. A timed semiconductor relay controls the operating cycle of the sampling pump to prevent foreign matter from being drawn in when the fresh air fan is powered off. The sampling tube adopts anti-static PU polyurethane hose, which effectively avoids particulate
