- 儀器介紹
- New development based on more than 10 years of experience in bubble
pressure measuring technique. Many new instrumental details have been
published recently, such as the determination of bubble time
characteristics from the gas flow signal.
Four different measuring modes available.
Process controlling option on board.
BPA-1P is the simplified version of the BPA-1S representing the high end
instrument in bubble pressure tensiometry.
Two different displays - text or graphic - available.
軟件
BPA-1P operates as stand-alone instrument. It
stores data on board for 180 measurements.
Data download from the instrument to a PC via
RS-232 or USB port. The software allows
graphical display of several measurements for
comparison. Graphics with various zoom
functions supports the visual analysis of the data.
Export as text file or directly into MS Excel.
