Quality control is an essential part of the production process, as it ensures that the products meet the required standards and specifications. An important tool that aids quality control professionals is the cross hatch tester. In this article, we will talk about the SAMA Tools name-brand SADT535 Automatic Cross Hatch Tester and the advantages it offers over its manual counterparts.

It’s a device designed to evaluate the adhesion of paints to substrates. It’s an accurate and reliable method for determining the durability of the substrate adhesion to paints and coatings.  In addition, it can also be used to perform pass/fail tests and evaluate the adhesion between different coats of paint.

What are the advantages of using an automatic cross hatch tester?

Test repeatability:

The automatic cross hatch tester ensures that tests are repeatable thanks to the consistant speed and force of the cut.  By eliminating human/gross errors, the likelihood of unreliable or inconsistent results is greatly reduced.

Cuts and scoring are uniform:

This device guarantees a uniform and consistant cut, making it easier to evaluate the adherence between the different layers of paint. The consistency of the cut allows a precise comparison of the results and helps to identify any defects or irregularities.


This instrument improves quality control efficiency because it saves time and resources compared to the manual method. This tool allows testing to be done quickly and accurately, freeing QA professionals to focus on other important tasks.

What are the reference standards for the cross hatch tester?

We are talking about a device that complies with ISO 2409 and ASTM 3359 standards, which offers many advantages compared to similar products on the market:

  • 7-inch industrial touch screen: The device is equipped with a large touchscreen, that allows you to easily change the cutting parameters and view them clearly and intuitively.
  • Parameter customization: The cutting speed, load, cutting intervals and number of cuts (horizontal and vertical) can be set according to the test specifications.
  • Automatic Load Compensation: During the cutting process, the tester automatically compensates the load force to ensure that the load remains consistant and the depth of cut even, on the coating surface.
  • Automatic sample locking: The test sample is automatically locked into place, simplifying the procedure and ensuring correct positioning for the duration of the test.
  • Automatic Rotation of the Working Platform: After the first series of cuts are completed, the working platform automatically rotates at an accurate 90°. This automatic rotation is very important because it prevents the cut lines from overlapping and crossing each other in the wrong direction.

Therefore, the SAMA Tools automatic cross hatch tester offers a reliable, precise and efficient test experience to evaluate the adherence of coatings.
