The OPAC20/20 double pass opacity monitor uses a green light emitting diode (LED) light source. The low powered solid state light source emits negligible heat and is electronically modulated, eliminating chopping mechanisms and their inherent problems. High frequency modulation creates a more stable opacity response and eliminates the ambient light interference found in low frequency modulation of incandescent lamp opacity monitors. The long life of LED's , creates a trouble free optics assembly. The OPAC20/20 opacity monitors' LED has an expected life of ten years.
