重慶四川供應TSI 8177光散射光度計產品概述：

8177型光度計是任何8130和8127過濾器測試儀的改裝選項。光散射光度計是呼吸過濾器和過濾介質測試中檢測器的優選。光度計具有非常高的動態范圍和靈敏度，因此可用于測量高達99.9999％的過濾效率而無需稀釋。8177型光度計現在可由用戶和現場維修，使用戶能夠安排先發制人的維護，對生產和測試計劃的影響*小。

TSI的自動過濾器測試儀和的監管機構以及數百家制造商使用高質量的光度計已有20多年的歷史。8177型光度計可由技術人員在不到一小時的時間內在現場進行清潔（參見左側視頻）。諸如鍵入組件之類的設計改進消除了維護后校準的需要。以前清潔光度計需要將它們送回工廠，耗費時間和**。用戶可維修的8177型光度計使您可以控制何時進行維修，*大限度地減少停機時間，降低擁有成本并實現更有利可圖的過濾器測試。

重慶四川供應TSI 8177光散射光度計產品性能特點：

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TSI 8177光散射光度計產品工作原理：

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.
