重庆四川供应TSI 8177光散射光度计产品性能特点：
The background light level is determined by feeding filtered air into the chamber. The background increases when the surfaces become coated with particles. Eventually, the photometer needs to be cleaned in order to restore the background to previous levels.
+ A sheath air system significantly reduces the contamination inside the photometer. It works by isolating the aerosol stream with a surrounding clean air stream. This keeps the sampled aerosol away from the optical components inside the scattering chamber.
+ An effective and optimized beam stop terminates the light that passed through the measuring volume.
+ Light absorbing coating further minimizes background light scattering in the chamber. This coating can now be cleaned in the field.

重庆四川供应TSI 8177光散射光度计产品工作原理：
Filter Tester Models 8127 and 8130 house two light-scattering laser photometers to simultaneously measure the upstream and downstream aerosol concentration levels. The signal from the photometers is a voltage that is proportional to particle concentration. Particle penetration through a filter is determined by dividing the downstream voltage by the upstream voltage. By using two laser photometers instead of one, measurement accuracy and throughput (due to faster testing) is increased.
The laser photometer scattering chamber of the high-resolution photometer is shown at the right. The light from a laser diode is focused with a collimating lens and a series of apertures to create a defined beam diameter at the measuring volume. The air sample then passes through the measuring volume and scatters light relative to the amount of aerosol in the air stream. The scattered light is collected by two aspheric lenses and is focused onto a photodiode detector, allowing the user to obtain the relative concentration measurement.
