The automatic interfacial tension tester complies with GB/T6541 and ISO6295. It uses the ring method to measure the surface tension of various liquids and the interfacial tension between mineral oil and water under non-equilibrium conditions, and can reliably indicate the existence of hydrophilic oxides.
Technical features:
Adopt dual CPU microcomputer control
Use equal interval multi-point calibration to correct the nonlinearity of the electromagnetic force balance sensor to ensure measurement accuracy
Automatically collect the current temperature and automatically calculate the temperature compensation for the test results
After the test is completed, the test results are automatically stored, and 255 more can be stored
Perpetual calendar clock, automatically record the date and time of measurement. The power-off storage time is 10 years
With screen protection function, prolong the life of LCD
There is an RS232 port for communication with the computer
