Hardness Testing Instrument Zwick 3105 Combi Test IRHD/Shore

The Zwick 3105 combi test is a microcomputer-controlled hardness testing instrument with very high measurement accuracy in several IRHD (and IRHD-ss supersoft) and Shore measurement ranges. 
 
Operator error is eliminated; the Zwick 3105 delivers quick, fully automatic measurement in all Shore and IRHD ranges with high measurement accuracy thanks to its digital measuring systems. It can perform hardness tests on mouldings and sheet materials, for example using an automatic test sequence. 
 
Before the spring load for Shore testing or the main load for IRHD is applied, the indentor scans the surface of the specimen. This patented procedure helps guarantee reliable measurements on moldings with concave or convex surfaces.
