Ink and pen of surface tension

Our inks and test pens make it possible to optimize the control of surface treatments and ensure the degree of degreasing of metal surfaces. Our test inks are available in different containers, widths and values.


They are also available in standard set.

  • Quick and easy surface search on all materials (except wood).
  • Control of surface treatments on all materials (except wood).
  • Checking the degree of degreasing of metal surfaces.
  • Manufactured in pens or flasks. Bottle in 10 ml with brush built into the lid.
  • Pen with anti-drying valve. Available in 5, 8, 15, 20 and 60 mm wide.
  • Free declaration (REACH, GHS).
  • Available from 16 to 105 mN / m. No medical risk for the user.
  • Highly ecological product.
  • Patented product.

Preparation temperature

From 18 ° C to 23 ° C. Inks have a boiling point> 100 ° C, which allows you to make measurements at temperatures of 50 ° C and above.

At lower temperatures the indicated surface tension values ​​are lower than the room temperature measurements whereas at higher temperatures they are higher than these measurements. As approximate indications, the variations are estimated at between 1 and 2 mN / m per 10 ° C increments.



  • from 16 ° C to 25 ° C – protect from direct sunlight.
  • hermetic closure – in a sufficiently ventilated place.


Kept in the dark at a temperature between 16 ° C and 25 ° C for at least 6 months from the date of opening and at least 12 months from the date of filling.
