The method for detecting condensation characteristics provided by this invention involves multiple tests on the same sample, with state parameter values ​​as variables. Each single test step involves first adjusting the test rod to the initial sinking position [M], then allowing the test rod to freely sink from the initial sinking position [Me] while a timer starts timing [Sr]. The timer stops timing [Sp] when the test rod sinks to the characteristic depth [Cd], and the timing value [Ti] is obtained as the sinking time for this test. Finally, the state parameter value of the measured characteristic point is calculated using the data sequence of the relationship between the measured sinking time at the characteristic depth and the state parameters. Compared with existing technologies, this invention replaces the method of measuring the sinking depth of the test rod within a fixed sinking time with the method of measuring the sinking time at a fixed sinking depth, improving the convenience and reducing the cost of error control. The Vicat apparatus developed accordingly is low-cost, simple to operate, and has lower error.
