BPA2P
The BPA2P is a mobile bubble pressure analyzer with a built in computer and storage so that this instrument can even be used off-line in field studies. It determined the hydrostatic component of the measured total pressure automatically so that surface tensions can be easily obtained. The available time range is between 10 ms and about 10 s, with an excellent accuracy and reproducibility.
New developments based on modern hardware and software design expands the instrument’s usability and measurement performances.
New improved compact mechanics increases significantly the reliability and stability of the instrument.

Instrumental parts
The BPA-2P uses modern high quality electronic and
mechanic components. This results in a better measurement
accuracy and measurement stability. User interface provided
touch screen functionalities and optional possibilities to use
external mouse/keyboard connected with the instrument via
USB port. There is built-in RTC.
The instrument allows the following measurements
- surface tension of liquids
- density estimation
Main features of the software
BPA-2P based on a built-in modern OS Embedded Linux and operates as stand-alone instrument. It contains built-in FTP and VNC servers for sharing the measurement data and remote control over Ethernet network. You could easily get access to BPA-2P via any external PC/Notebook. Internal . All instrument’s functions are supported without external PC connections. As user interface a touch screen provides functionalities and optional possibilities to use external mouse/keyboard connected with the instrument via USB port. USB 2.0 interface and built-in SD-slot allows storing the measurement data on a USB stick or SD card. An Ethernet interface allows connection of the instrument directly to a local network. The instrument control from a PC via local net or internet is possible.
