DH400ACDCIHT is designed for interior
or exterior duct applications where extreme temperatures
can exceed standard detector capabilities. (For exterior
applications use DH400 OE-1 outdoor enclosure.) The
DH400ACDCIHT samples air currents passing through aduct to provide dependable performance for management
of fans, blowers, and air conditioning systems. The twist-in,
twist-out 1451DHHT High-Temperature ionization detector
head allows easy removal for quick cleaning, maintenance,
and replacement without removing the duct housing.
