− Features

  • Constant Force Application: Central to the kit is the Pencil Cart, which exerts a mechanically regulated, constant force of and maintains the mandatory angle, making results highly repeatable and compliant with standards.
  • Leveling Rod Included: Comes with a Leveling Rod to confirm the Pencil Cart is perfectly parallel to the test surface, further guaranteeing that the force and angle are applied correctly throughout the stroke.
  • Full Hardness Range: Supplied with the complete set of certified graphite pencils (from to ), enabling the precise determination of the hardest pencil that does not damage the film.
  • Precision Conditioning Tools: Includes a custom aluminum pencil sharpener with integrated and reference marks, along with grit sandpaper, to ensure the pencil leads are conditioned exactly as specified by test standards.
  • Durable Carrying Case: The entire Complete Kit, including the Pencil Cart and all accessories, is stored in a rugged hard-shell carrying case for secure transport and organization in demanding field environments.

What is the unique advantage of the Pencil Cart in the Complete Kit?

The Pencil Cart ensures the test is performed with a constant and verifiable force of at the specified angle, dramatically improving the repeatability and accuracy over manual methods.

What is included in the PosiTest PT Complete Kit that is not in the Basic Kit?

The Complete Kit (PTKITC) adds the Pencil Cart with Leveling Rod and a hard-shell carrying case to the standard set of pencils and sharpening tools.

Does the Pencil Cart support quick changes of test pencils?

Yes, the Pencil Cart is designed with a convenient thumbscrew mechanism that allows for rapid and secure changes of the test pencils during the evaluation process.

How is the lead prepared before using the Pencil Cart?

The test pencil lead must be prepared using the custom sharpener and then flattened using the included grit sandpaper to conform to the required testing geometry.

What is the primary function of the Leveling Rod accessory?

The Leveling Rod is used to confirm that the Pencil Cart is positioned parallel to the test surface before the stroke is performed, ensuring the applied force angle is consistently .
