Electrostatic Dust Monitor
201LP - Datatest Inc (Redkoh Industries, Inc.)
The Redkoh Model 201LP is a three wire particulate monitor that measures particulate levels in air ducts on a real time basis. The Model 201LP is powered by an external 24V dc supply and its continuous 4-20 ma output can be connected directly to a PLC, recorder, or digital readout. Changes in the 4-20 ma output are directly related to changes in the concentration of particulate in the gas stream.
