Proceq

<h2 id="history">History</h2>
<p>Proceq SA was founded on 8 April 1954 by Antonio Brandestini, when it opened its first office in Zurich, Switzerland. During its early years, the company concentrated on developing and selling special equipment for <a href="/facts/Prestressed_concrete/0fFlgCju">
pre-stressed concrete engineering</a>, a field which was, at that time, in its infancy. It also developed bearings for the construction industry. The introduction of the original <a href="/facts/Schmidt_hammer/tM8NNyL0">Schmidt concrete test hammer</a> was a significant event in the company's history and in the years that followed the company evolved to focus entirely on portable <a href="/facts/Nondestructive_testing/Czz0Vt0B">nondestructive testing</a> test instrument. 
All manufacturing is based in <a href="/facts/Switzerland/LcGuxeTe">Switzerland</a>, but Proceq has subsidiaries in Europe, Asia, the Middle East, the US and South America.<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a>

<h2 id="research-and-development">Research and development</h2>
<p>Proceq has its own research and development team, based at the headquarters in Switzerland. Two major patents have been produced by this team. The first was the Original Schmidt test hammer, the second was the <a href="/facts/Leeb_rebound_hardness_test/dPCX6uKg">Leeb rebound principle</a> (named after the Proceq scientist Dietmar Leeb). This principle is employed in the Equotip metal hardness tester.<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a>
Both of these Proceq innovations have been recognized by international standard bodies such as <a href="/facts/ASTM_International/xzdCexYJ">ASTM</a>, <a href="/facts/International_Organization_for_Standardization/IacYR7Yg">ISO</a><a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a> and the <a href="/facts/List_of_EN_standards/7304b0fN">EN standards authority</a>.
In recent years, Proceq has expanded into the fields of imaging with <a href="/facts/Ultrasonic_testing/MNBrJjuP">ultrasonics</a> and <a href="/facts/Ground-penetrating_radar/5pUWHTfP">GPR</a> of concrete structures.
