MetalTek™ Rockwell Hardness Tester Model PR1
MetalTek™ Portable Model PR1
MetalTek™ Model PR1
MetalTek™ Metal Hardness Testers by CCSi
The MetalTek™ PR1 Portable Rockwell Hardness Tester is lightweight, portable easy to operate and accurate. The PR1 is designed as a convenient means by which to determine Rockwell Hardness readings in situations that do not lend themselves to bench testing.
The PR1 is secured to the work piece by a quality clamping mechanism. It utilizes a mechanical mechanism to apply the major and minor loads. Since the PR1 employs no weights, it may be used in virtually any position.
The PR1 is ideal for testing stacked sheets, rod and tubing in racks and in areas where clearance is limited.
The PR1 employs major loads of 60, 100 and 150 kg and has a maximum height capacity of 110 mm (4.3 in) and a throat capacity of 55 mm (2.2 in).
The PR1 features a “pistol grip” for ease of operation and speed in performing tests.
