The beginnings of the MRU


Foundation of the company MRU – Messgeräte für Rauchgase und Umweltschutz – by Erwin Hintz on 1st, June 1984 in Heilbronn, Germany.


1st, October 1988 the German 1.BImSchV (Small Combustion Plant Directive) came into effect, which entitled the chimney sweepers to carry out emission measurements at small combustion plants. The demand for flue gas measuring units multiplied almost overnight. Industrial systems, which were basis of the founding-idea, lost importance in the market. A new generation of measuring units had to be developed.


Foundation of the first subsidiary in Austria.


Opening and move to the first own premises in Neckarsulm-Obereisesheim. At this time, MRU employed about 50 people and the first industrial gas analyzer is sold.

MRU worldwide


A worldwide revision of attitudes towards environmental protection began. The German laws “TA-Luft” and 1.BImSchV many times served as guidelines in that process. However, the driving power was not always the intent of environmental protection rather than saving energy. New markets grew. New analyzers, often tailored to country - specific requirements, were developed. MRU Emission Monitoring Systems are being exported in more than 70 countries worldwide. From a quite small beginning, our company developed into a medium-sized, globally acting and very successful enterprise.

Foundation of the second German service center in Markt-Schwaben, Bavaria, and foundation of the subsidiaries in the USA and Slovenia.


MRU sets standards


Introduction of our SPECTRAplus multifunctional measuring instrument for the chimneysweeper market in Germany. At the same time, we were introducing our OPTIMA7 industrial hand-held measuring instrument in the export market. With both devices, we were able to set standards. With our OPTIMA7 it is possible to analyze up to seven gas components in parallel, and the SPECTRAplus still is the benchmark in the market.


In 2012, a new facility, 2.500m² in size and equipped with most modern manufacturing possibilities, went into operation. 


Foundation of the subsidiary in Russia.
