BPA2S是我们BPA仪器的高端版本，可以在非常宽的时间间隔内提供动态表面张力。根据Fainerman在1990年提出的一项特定协议，可以准确地将死区时间与气泡的寿命分开，这允许在从小于1毫秒到气泡表面年龄约100秒的时间间隔内获得动态表面张力数据。这六个数量级的时间范围可能是单个仪器张力测量中最宽的。当运行一天以上的测量时，PAT在时间上只覆盖了五个数量级，而两者相辅相成，提供了从t<1ms到24小时甚至更长的时间窗口。在极短的吸附时间内进行测量的可能性，甚至可以研究与喷墨打印或快速涂层等快速过程相关的研究，并深入了解胶束形成/溶解动力学等快速过程。
高端最大气泡压力张力计，用于在亚毫秒范围内精确测量表面张力。
基于现代硬件和软件设计的独立仪器，采用高性能嵌入式计算机，扩展了仪器的可用性和测量性能。
现代用户友好的界面和连接简化了仪器的操作。
