BPA2S是我們BPA儀器的高端版本，可以在非常寬的時間間隔內提供動態表面張力。根據Fainerman在1990年提出的一項特定協議，可以準確地將死區時間與氣泡的壽命分開，這允許在從小于1毫秒到氣泡表面年齡約100秒的時間間隔內獲得動態表面張力數據。這六個數量級的時間范圍可能是單個儀器張力測量中最寬的。當運行一天以上的測量時，PAT在時間上只覆蓋了五個數量級，而兩者相輔相成，提供了從t<1ms到24小時甚至更長的時間窗口。在極短的吸附時間內進行測量的可能性，甚至可以研究與噴墨打印或快速涂層等快速過程相關的研究，并深入了解膠束形成/溶解動力學等快速過程。
高端最大氣泡壓力張力計，用于在亞毫秒范圍內精確測量表面張力。
基于現代硬件和軟件設計的獨立儀器，采用高性能嵌入式計算機，擴展了儀器的可用性和測量性能。
現代用戶友好的界面和連接簡化了儀器的操作。
