Water Drip Diffusion Time Tester RF4008WDDT

The Water Drip Diffusion Time Tester tests the time required for a certain amount of water to drop onto the surface of an absorbent sample until it is completely absorbed (its reflection disappears).

Wetting refers to the time it takes for a drop of water to lose its light reflection properties, that is, when it becomes a dull, damp spot due to the absorption tendency of the textile material.

Absorbability refers to the tendency of a material to absorb and retain liquids (usually water) in pores and voids.

Test method: Fix the sample on the sample clamp, place the sample clamp horizontally, with the test surface of the sample facing upwards. At a certain height from the test surface, drip water to the surface of the sample, and test the time required for the diffusion of water droplets.

RF4008WDDT is a sensor that detects the diffusion of dripping water, placed at a height of about 10mm at the dripping position above the sample. When the dripping device drips water to the sample, it begins to detect the diffusion time.
