Head Nose Only Units   頭鼻式單元

Our Head Nose Only exposure units have a modular expandable design which allows them to be continually adapted to the customer's requirements. The basic structure consists of single segments which can be stacked on top of each other.
我們的頭鼻式暴露單位采用模塊化和可擴(kuò)展設(shè)計(jì)這使他們能夠不斷調(diào)整以適應(yīng)客戶的需求。基礎(chǔ)結(jié)構(gòu)包括各個(gè)單個(gè)分層，可以逐層堆疊。

The validation of the equilibrium distribution and directed-flow design was carried out in 1994/2007 by Prof. Pauluhn, and in 2009 by Prof. Phalen.
Pauluhn教授（1994年和2007年）和Phalen教授（2009年）驗(yàn)證了系統(tǒng)的平衡分布和直通氣流設(shè)計(jì)

Each Head Nose Only exposure unit can be equipped with the required aerosol inlet interfaces, appropriate animal cage ports, sampling and environmental sensor connections / adaptors.
每個(gè)頭鼻式暴露單元可以配備需要的氣溶膠入口，適當(dāng)?shù)膭?dòng)物籠子端口，取樣和環(huán)境傳感器連接/適配器。
