Visable Emission Monitor 252

Skil Emission Monitors are designed to measure dust and smoke discharged
from Furnaces, Incinerators, Boilers and industrial plant. Satisfying legal
requirements to monitor smoke and particulate emissions into the
atmosphere.
The Model 252 Visible Emission Monitor may be used to continually
monitor and display optical density or opacity, and will also display
particulate emissions when calibrated on the ISO-kinetic sampling principle
as described in BS893 and BS3405.
The equipment comprises a digital indicator control unit suitable for panel
mounting, transmitter and receiver units, complete with extension tubes for
mounting to the flue or stack.
The Monitor can also be used to measure other opaque fluids, such as fume
