Gas opacity meter SENTRY

SENTRY is an electro-optical sensor whose function is to measure opacity in the air through the existing particles (suspended particles, gas emissions, etc.). It uses the forward scatter principle, capturing a sample of light at an angle of 42º. The amplitude of this angle allows detection of particles of great size. The advantages of SENTRY when compared to other opacimeters are: Does not need to be calibrated on installation External vibrations do not affect the calibration of the sensor It uses a forward scatter principle, when compared to other opacimeters that use less effective technologies like back scatter
