PS25 Hardness Tester Calibration Slides — Vickers/Rockwell

Reflected light calibration slide with diamond shapes and scales for calibrating Vickers and Rockwell hardness testers

For Vickers and Rockwell methods, we offer the PS25 which has a series of diamond shapes of varying size and x-y scales. Each of the markings on the slide is clearly identified with its size. The PS25 has a glass disc with the image precision marked in vacuum deposited chrome, and this is cemented into a stainless steel slide mount, making the item very durable. The slide has a unique serial number indelibly marked on the slide mount and can be supplied with an Internationally traceable certificate of calibration.

PS25 Pattern Detail:

Diamonds: (Point to point, mm) 0.5, 0.3, 0.2, 0.1. 0.05. 0.02 Scales: Horizontal & vertical, 2mm in 0.1mm divisions

PS26 Hardness Tester Calibration Slides — Brinell

Reflected light calibration slide with circle shapes and scales for calibrating Brinell hardness testers

For Brinell methods, we offer the PS26 which has a series of circles to represent the ball indentation shape of varying size and x-y scales. The PS26 has a precision marked chrome deposition image on a glass slide. Each of the markings on the slide is clearly identified with its size. The slide can be supplied with an Internationally traceable certificate of calibration.

PS26 Pattern Detail:

Circles: (Diameter, mm) 5.0, 2.5, 1.0, 0.7, 0.3 Scales: Horizontal & vertical, 2mm in 0.1mm divisions
