The Dust Detect 1000 is a single device dust detector that has been specifically designed to continuously monitor the flow of particulate emissions from small stacks or other emission points being passed through a filter within an air filtration system. It easily installs in the exhaust ductwork and can be used in conjunction with various types of bag, ceramic, cartridge or cyclone filters. The probe on the Dust Detect 1000 is designed to recognize abnormal particulate levels outside user-defined preset parameters and initiates an alarm when changes in emission exceed these levels.
