XZD-3Surface tension meterThe measurement adopts a digital imaging acquisition system, and the video optical system is controlled by a computer to move left and right to track the droplet and collect images. The droplet images can be photographed and stored at regular intervals according to user experimental requirements, and the interface tension value can be measured and calculated. The curve of time and interface tension, as well as the width and time curve, can be drawn, greatly improving the measurement accuracy, eliminating human reading errors, and greatly reducing the workload of researchers.

XZD-3Surface tension meter

In order to better meet the requirements of users, Beijing HARKE has summarized years of production practice experience in the field of interface science, continuously improved and perfected the performance of the rotating droplet boundary (surface) tension meter, and developed, designed, and manufactured new models. The new model has made significant progress in stability, ease of operation, noise, automation, and testing methods.

XZD-3Adopting an open design, the degree of virus damage is minimized, the interface is beautiful, bright, easy to operate, the operation information is displayed clearly, and the horizontal and vertical point taking and moving strip line measurement methods are used. During the testing process, the small window movie image displays each captured photo, with dynamic switching between large and small windows. This allows for the measurement of random image information or saved image measurements during the experiment, displaying the time coordinate curve, width and time curve.

XZD-3Main features:

lThe tension measurement range is wide and can measure up to 100-1-10-7mN/m.

lIt is convenient to measure the contact angle between liquid and solid. Thus conducting research on wettability.

lEquipped with CCD automatic/manual control translation mechanism, it is convenient to observe the position and shape of droplets during sample loading.

lThe key component micro motor is imported from abroad, and the spindle adopts a direct connection structure to prevent loss of rotation, resulting in more stable speed.

lDual heating mode can be used for internal heating measurement or external circulating water bath temperature control

lThe software interface is beautiful and elegant. Easy and flexible operation. Accurate testing. It has functions such as timed screenshot, video recording/playback, timed photography, and curve generation
