Smart environmental monitoring solutions
For applications requiring absolute value measurements of dust concentrations, the S304 can be calibrated to give the user an mg/m3 output. Once calibrated, this dust monitor helps plant operators know exactly how much dust is passing through the stack or outlet duct of their plant.
The S304 is additionally equipped with a 4-20mA signal and two independent alarm relays that can be used to further optimize process conditions in the plant
