IRHD & Shore hardness tester

Combined IRHD / Shore hardness tester

The ZwickRoell 3105 combi test is a microcomputer-controlled hardness tester with very high measurement accuracy in multiple IRHD (plus IRHD ss supersoft) and Shore measurement ranges. The combi test hardness tester is suitable for standard compliant testing in accordance with ASTM D2240 & ISO 48-4, ISO 868, NFT 51 123, NF 46 003 and ASTM D1415 & ISO 48-2.

Applications and advantages

Applications

The ZwickRoell 3105 combi test is a microcomputer-controlled hardness tester for the following measurement ranges:

IRHD-M (micro)
IRHD-N (normal)
IRHD-H
IRHD-L (soft)
VLRH (IRHD supersoft)
Shore A/B/0
Shore D/C/D0
Shore 00/000
Micro Shore

It is compliant according to: ISO 48-4, ISO 7619-1 (withdrawn), ISO 868, ASTM D2240, ASTM D1415, NFT 51 123, NF 46 003.

Advantages and features

Quick and high measurement accuracy without operator influences via automatic measurement procedures
Reliable measurements on shaped parts with concave or convex surfaces, e.g. hardness tests on prefabricated parts
Modular construction with automatic identification of the measurement system and the adjustment of the measurement distance
Intuitive display with easy operation
Wide range of accessories, e.g. for quick centering of O-rings and hoses

IRHD & Shore hardness tester accessories

Measuring devices

Multiple measuring heads are available for the various ranges of application; changeover is quick and easy via a single screw.

Specimen holders

The following specimen holders are available: 1) Rapid centering device for O-rings (material diameter 0.6 to 5 mm) 2) Movable retaining block with prism for exact centering of hoses; can be attached to the test table 3) Magnifier with swivel arm

Calibration certificates and rubber test sheets

Calibration certificates (e.g. DAkkS) are available for all measuring devices and indenters on application. Also in ZwickRoell's product range: rubber test sheets for indirect verification of your hardness tester.
