BYK hardness tester DUR-O-Test

BYK Gardner Hardness Tester DUR-O-Test Purpose and Application:

This instrument is designed to measure the hardness of protective coatings. The hardness of paint films and plastic coatings can be accurately measured and recorded using this type of hardness testing rod, and the measuring surface can be flat or curved, regardless of size. The instrument is always in standby mode. It can be carried in a pocket and used for various hardness tests.

BYK Gardner Hardness Tester DUR-O-Test Test Procedure:

The portable hardness test rod is particularly easy to use. The estimated or known spring pressure can be set through the sliding rod. Place the instrument vertically on the testing surface and draw a 5-10 mm straight line at a speed of 10 mm/sec. The test head will produce a scratch that is only visible to the naked eye. If the spring pressure is too high, scratches will be very clear, and if the spring pressure is too low, no scratches will appear. By locking the slider, the required pressure can be controlled each time, in newtons.

The scale engraved on the pen includes three pressure ranges, and each spring corresponding to the pressure range has a color code corresponding to the scale:

0-3N (silver mark) 0-300g, spaced 10g apart

0-10N (marked in red) 0-1000g, spaced 50g apart

0-20N (marked in blue) 0-2000g, with an interval of 100g

BYK Gardner Hardness Tester DUR-O-Test Maintenance and Repair:

A clean instrument can produce a clean test result. To clean, loosen the nut and remove the scale pen. Clean the rod and hole with a soft cloth. In addition, the instrument does not require further maintenance.

Although the structure of the hardness test rod is sturdy, the test head cannot withstand significant impact. The wooden box accompanying the instrument provides such a protective function. When not in use, the slider should be set to zero position to protect the accuracy of the spring.
