Esatest MTR is the result of more than 40 years of experience and continuing research into new technological solutions to problems in the hardness testing of metals. It is a new hardness tester that measures electrical resistance.
Esatest MTR has been designed as a solution to previously unresolved problems in hardness testing, particularly for testing in places that were inaccessible until now. Thanks to a new, patented system of impression reading, Esatest MTR requires neither optical reading of the impression nor measuring of penetration depth. It can perform testing in all positions with minimum difficulty and without special stability.
Readings are provided on the display in Vickers, Rockwell C and other scales upon request.
With Esatest MTR, the load is applied progressively. So with one test, different hardness values conforming to the entire range of applied loads can be observed.
This solution is very useful for testing superficially treated specimens. It allows a quick evaluation of the depth of the superficial treatment and possible rectification of ground parts.
The new system measures electrical resistance between the mounting of a diamond indenter conducting electricity and the contact limit between the indenter and the surface of the specimen during penetration (see working scheme at right).
This resistance decreases as penetration increases and the penetrator acts as a probe to determine the dimensions of the impression.
Esatest MTR is limited to use with metals only.
This new principle of hardness measuring permits testing in the most difficult or previously inaccessible locations.
The wing of a supersonic plane, the wishbone of a Formula One race car, a turbine blade and a wheel joint are only some of the “difficult” applications that Esatest MTR can handle, issuing data with a detailed comparative diagram.
