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(hù)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?。?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 deliverhighly accurate and reproducible dynamic surface tension measurements in under6 minutes. Dynamic surface tension measurements provide information on thewetting properties of the liquid. This data is useful for controlling anddeveloping the surface active agents for a number of processes such asprinting, spraying, cleaning and coating. BPA-800P also enables direct andprecise determination of bubble lifetime characteristics, providing insights ondiffusion and absorption coefficient of surfactants. With unknown liquidsamples, the BPA-800P is able to accurately correct for and estimate sampleviscosity and gravitational deformation of bubble shape. BPA-800P has theability 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 friendlyinstrument. The liquid surface is automatically detected and the capillary islowered to the appropriate level. Data is stored in integrated memory, and canbe uploaded onto a computer. The included software also enables operating theBPA-800P with a computer as well as performing data analysis. Results can bepresented as a function of measurement time and effective adsorption time.Portability and battery operation make the instrument extremely useful inindustrial and environmental applications.
