Dynamic Bubble Pressure Tensioner

When the FDT600 series dynamic bubble pressure tensiometer continuously increases the rheological rate of gas, the frequency of bubble formation increases and the survival time of each bubble decreases accordingly. It can automatically scan the number of bubbles and tension curve, and can also measure the tension value of the set number of bubbles individually. When the bubble radius at the end of the capillary is equal to the capillary radius, the bubble pressure reaches its maximum value. Once the bubble radius exceeds the capillary radius, the bubble pressure significantly decreases. The maximum pressure at which bubbles are generated is directly proportional to the dynamic surface tension. The hydrostatic pressure P is directly proportional to the immersion depth of the capillary tube.
