OP Series - Opacity
Particulate Emission Monitor
To padronize the evaluation of gas effluents, EPA (Environmental Protection Agency), in 1971 approved the method 9 - Ringelman Scale.
The Opacimeter or particulate monitor is designed to comply with all the conformities of EPA- CFR, part. 60, Appendix b, Performance Specification.
Analytical Methods for monitoring of Particulated Monitor emissions:
• Emission Monitor - ON-SITU
• Determination of Particulated Material from Stationary Sources in Pipes and Chimneys - Isokinetic Sampling
Assuming that the measurement of opacity does not express Concentration , but only Turbidity of the gases, to establish a connection with the concentration of particulates, it becomes necessary to know:
• Active Optical Step
• Particle size and particle nature
• Measurement range - concentration value to be monitored
