重慶四川供應(yīng)TSI 8177光散射光度計(jì)產(chǎn)品概述：
8177型光度計(jì)是任何8130和8127過(guò)濾器測(cè)試儀的改裝選項(xiàng)。光散射光度計(jì)是呼吸過(guò)濾器和過(guò)濾介質(zhì)測(cè)試中檢測(cè)器的優(yōu)選。光度計(jì)具有非常高的動(dòng)態(tài)范圍和靈敏度，因此可用于測(cè)量高達(dá)99.9999％的過(guò)濾效率而無(wú)需稀釋。8177型光度計(jì)現(xiàn)在可由用戶和現(xiàn)場(chǎng)維修，使用戶能夠安排先發(fā)制人的維護(hù)，對(duì)生產(chǎn)和測(cè)試計(jì)劃的影響*小。
TSI的自動(dòng)過(guò)濾器測(cè)試儀和的監(jiān)管機(jī)構(gòu)以及數(shù)百家制造商使用高質(zhì)量的光度計(jì)已有20多年的歷史。8177型光度計(jì)可由技術(shù)人員在不到一小時(shí)的時(shí)間內(nèi)在現(xiàn)場(chǎng)進(jìn)行清潔（參見(jiàn)左側(cè)視頻）。諸如鍵入組件之類的設(shè)計(jì)改進(jìn)消除了維護(hù)后校準(zhǔn)的需要。以前清潔光度計(jì)需要將它們送回工廠，耗費(fèi)時(shí)間和**。用戶可維修的8177型光度計(jì)使您可以控制何時(shí)進(jìn)行維修，*大限度地減少停機(jī)時(shí)間，降低擁有成本并實(shí)現(xiàn)更有利可圖的過(guò)濾器測(cè)試。
重慶四川供應(yīng)TSI 8177光散射光度計(jì)產(chǎn)品性能特點(diǎn)：
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.
重慶四川供應(yīng)TSI 8177光散射光度計(jì)產(chǎn)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.
