Surface tension measurement

Surface tension measurement with test inks and pens

FOR PLASTICS AND METALS

Test inks for surface tension measurement

Inks for a simple, fast and precise measurement of surface tension, even for rough or dark surfaces where it is always more complex to measure surface energy.

The measurement process consists of depositing the test ink from the bottle directly on the surface of the material to be verified, using a brush, pipette or cotton swab. Waiting a few seconds, the appearance of the deposited test ink will tell us if we have hit the surface tension value -that of the ink bottle being used- or we have to repeat the test with a test ink of more or less tension superficial.

Test ink bottles with a wide range of surface energy values. Error margin of +/- 1 mN/m

Test pens for measuring surface tension

Measurement is as simple as drawing a line with the test pen on the surface of the material to be measured.

Waiting a few seconds, the appearance of the line will tell us if we have hit the surface tension value -the value corresponding to the pen being used- or we have to repeat the test with a pen with more or less surface tension.

Accuracy and speed in the measurement, impossible ink spillage, low ink consumption and long conservation of the test liquid.

They are presented as sets of markers with different surface tensions, although they can be served separately. Measurement accuracy: +/- 1 mN/m.
