"SITA-online" is a Windows program for recording and editing data from the world's first hand-held instruments for measuring the dynamic surface tension of liquids: The SITA pro line f10 and SITA science line t60.

The program "SITA-online" is capable of:

• recording all data online (surface tension, temperature, bubble frequency and bubble lifetime),
• plotting the readings versus the elapsed time, current time, number of readings, temperature, bubble frequency or bubble lifetime,
• saving all data,
• exporting the data to ASCII format,
• printing plots and data lists,
• controlling the device and
• recording data from up to 8 instruments simultaneously.

"SITA-online" also offers a comprehensive help function which explains the use of the program.

The program "SITA-offline" is capable of:

• plotting the measured surface tension (up to 128 measurements) in one window,
• plotting the measurement versus time, number of readings, temperature, bubble frequency or bubble lifetime,
• saving the plots and
• printing the plots.

The use of the "SITA-offline" program is explained in a comprehensive help function.

"SITA-online" and "SITA-offline" require the following hardware and software:
