Portable Contact Angle Meter

The Surface Analyst™  is a hand-held non-destructive portable contact angle meter for quantifying levels of surface preparation from the lab to the factory floor.

If you bond, paint, seal, coat print or clean, you probably experience problems getting what you apply to reliably stick to your surface.

The instrument widely used in the Automotive, Aerospace, Medical Device Manufacturing & Electronics industries works in a two second measurement cycle.   A small droplet of water is created on the surface from a pulsed stream of micro drops, with a single button operation the instrument  gives an immediate contact angle calculation or pass/fail indication from the drop diameter.  The results correlate directly to a material’s cleanliness and the potential to form a strong bond with an adhesive or coating.

  • Fast – in 2 seconds you can determine if your part is ready to bond, paint, seal, coat, print or is clean.
  • Easy – put the Surface analyst into production on the factory floor with as little as 15 minutes of training.
  • Accurate – a precise, repeatable measurement is delivered to the user, non subjectivity involved.
  • Non-Destructive – The Surface Analyst uses 1.5mL of highly purified water to take a measurement.
  • Pass/Fail Mode – Notifies you if the measurement is within your predefined Pass/Fail range.
