Anton Paar - Revetest Scratch Tester Get latest price

The Revetest® scratch tester series is the industrial standard, widely used for characterizing hard-coated materials with a typical coating thickness exceeding 1 μm. The RST series includes dependable instruments for the characterization of coating/substrate adhesion, surface scratch resistance, and conventional Vickers hardness. The software enables scratch tests in a wide variety of testing modes, as well as conventional Vickers hardness tests with automatic detection of the imprint. Anton Paar is the world leader in scratch testing with more than 1500 Revetest® Scratch Tester instruments sold.

 

Key features

Patented synchronized panorama mode

This unique feature is exclusive to Anton Paar scratch testers. It automatically synchronizes the recording of all sensor signals with the whole scratch image in perfect focus. This way, the measurement curve can be analyzed parallel to the scratch picture on one page. Anton Paar holds the patents US 12/324, 237, and EP 2065695 for the synchronized panorama mode.

Measurements on curved and uneven surfaces

Due to its unique force sensor control, the Revetest® scratch tester system detects every surface deviation and the active force feedback corrects it. By following the shape of the sample with total control of the desired load, RST instruments also perform reliable measurements on uneven and curved surfaces.

Unique conventional Vickers hardness capabilities

This unique feature automatically detects and measures the area of the imprint of a conventional Vickers test and eliminates user influence on the Vickers hardness test results. The RST series and other Anton Paar scratch testers are the only instruments on the market with such advanced capabilities in conventional Vickers hardness testing.

Compliant with ASTM C1624, ISO 20502 and ISO EN 1071

Anton Paar works closely with standardization organizations such as ISO, ASTM, DIN, and others, in order to support our customers to meet the high requirements they have for their own products. This is especially important  in quality control, where such standards are essential. By certifying our Revetest Scratch Testers accordingly, we can guarantee high-quality products and services in terms of safety, dependability, and sustainability.

High scratch measurement flexibility

Tips of different diameters and angles are available. Indenter holders are also available for applications where the use of small diameter spherical tips, Berkovich or Vickers tips, and those measuring 6 mm diameter, is required. One and the same indenter holder can be used for different kinds of tips, and one dedicated ball holder can be used for different ball materials.

Automatic detection of critical loads

Critical load data is used to quantify the adhesive properties of different film-substrate combinations by using different sensors (acoustic emission, penetration depth, friction force) and video microscope observations. With the new software, all critical loads can be detected automatically. The user only needs to set up threshold values and start the automatic analysis of the critical loads (Lc). The Revetest Scratch Tester series are the only scratch testers on the market with automatic detection of critical loads.
