New NDT solutions for metals, concrete and paper rolls
1975 – Proceq enters the metals testing sector in a big way with the introduction of Equotip, the first portable, non-destructive method for measuring the hardness of steel, iron, brass, aluminum and other metals. In the four decades since its introduction, Equotip has expanded to become a family of innovative products for easy and accurate testing of metals, including those with heat-treated and scratch-resistant surfaces.
Before Equotip, metal hardness measurement could only be done in a lab setting, where scientists conducted destructive tests on samples and drew statistical conclusions from the results. The introduction of Equotip enabled more extensive on-site testing without destroying samples, saving time and money while producing more accurate results.
1977 – Proceq scientist Dietmar Leeb publishes a paper explaining Equotip’s revolutionary approach to metal hardness testing, which he developed in concert with Marco Brandestini, the son of Proceq’s founder. To this day, the Leeb Rebound Hardness Test is the standard method for measuring the hardness of a wide range of metals, and the Equotip name is often used to describe Leeb rebound hammers in general.
1981 – Equotip is used as part of an investigation by NASA into debris from Skylab which was found in South West Australia.
1987 – Proceq introduces the Canin corrosion analyzing instrument, the forerunner to today’s more advanced Profometer Corrosion.
1988 – Proceq introduces the Torrent air permeability tester, which uses an innovative two-chamber vacuum cell to assess concrete quality.
1989 – Proceq offers its first product for the paper industry: the Parotester, which uses rebound technology to measure paper roll hardness. Today, Proceq offers two main products to the paper industry: the PaperSchmidt integrated rebound hammer for testing roll profiles; and the successor to the Parotester, the Equotip 550 Leeb U, designed for analyzing large rolls, thin foils and films.
