Smart environmental monitoring solutions
Continuous trend monitor that gives plant operators to see the performance of the filtration systems and ducts over a period of time. Perfect for installation after any filtration system or in common line channels leading into the emissions points of a plant.
State of the art Inductive Electrification principle minimizes the need for maintenance on the dust monitor and provides an accurate trend for end users. 4-20mA output combined with an easy-to-use auto-setup feature that takes less than 30 minutes from installation makes the device both convenient and reliable.
