In view of the deficiency existing in test method of original automatic interface tensiometer

some improvement measures have been suggested as follows: （1） adopting magnetic pot sealed sensor; （2） using equal-space multiple points’ calibration; （3） adding compensation function to the ambient temperature; （4） making the analysis method to be programmed by means of single chip processor. After improvement

the measuring accuracy of the said tensiometer has been greatly enhanced

solving the problem of test method stipulated in present National Standard having been restricted by the ambient temperature.
