氣泡張力儀BPA-800P是一個(gè)獨(dú)立的儀器能夠在少于6分鐘提供高度準(zhǔn)確和可重復(fù)性的動(dòng)態(tài)表面張力的測(cè)量。動(dòng)態(tài)表面張力的測(cè)量提供液體的潤(rùn)濕性能的信息。這個(gè)數(shù)據(jù)對(duì)控制和研究表面活性劑的一些過(guò)程，如印刷，噴涂，清洗和涂料是有用的。BPA-800P也可以直接精確氣泡的壽命特性。給表面活性劑提供恰當(dāng)?shù)牡奈蘸蛿U(kuò)散系數(shù)。對(duì)于不明液體樣品，BPA-800P可以準(zhǔn)確地糾正和估計(jì)樣品的粘度和重力變形氣泡形狀。bpa-800p有能力處理非常短以及足夠長(zhǎng)的測(cè)量時(shí)間（技術(shù)）。

自動(dòng)化程度高和簡(jiǎn)單使bpa-800p成為用戶友好的工具。液面自動(dòng)檢測(cè)和毛細(xì)管降低到適當(dāng)?shù)乃健?shù)據(jù)存儲(chǔ)在集成內(nèi)存，并可以上傳到電腦。被包括的軟件用電腦也可以操作bpa-800p，以及進(jìn)行數(shù)據(jù)分析。結(jié)果可以作為一個(gè)功能的測(cè)量時(shí)間和有效吸附時(shí)間。便攜性和電池操作使儀器在工業(yè)和環(huán)境非常有用。

Bubble Tensiometer BPA-800P is a standalone instrument able to deliver highly accurate and reproducible dynamic surface tension measurements in under 6 minutes. Dynamic surface tension measurements provide information on the wetting properties of the liquid. This data is useful for controlling and developing the surface active agents for a number of processes such as printing, spraying, cleaning and coating. BPA-800P also enables direct and precise determination of bubble lifetime characteristics, providing insights on diffusion and absorption coefficient of surfactants. With unknown liquid samples, the BPA-800P is able to accuray correct for and estimate sample viscosity and gravitational deformation of bubble shape. BPA-800P has the ability to handle extremely short as well as sufficiently long measuring times （patented technology）.

The high level of automation and simplicity make BPA-800P a user friendly instrument. The liquid surface is automatically detected and the capillary is lowered to the appropriate level. Data is stored in integrated memory, and can be uploaded onto a computer. The included software also enables operating the BPA-800P with a computer as well as performing data analysis. Results can be presented as a function of measurement time and effective adsorption time. Portability and battery operation make the instrument extremely useful in industrial and environmental applications.
