University of Vienna relies on high safety in CO gas detection


Today, the University of Vienna is one of the oldest and largest universities in Europe as well as the largest research and educational institution in Austria. The universities of Padua and Genoa were the inspiration for its construction. With 20 faculties for about 90,000 students, the University of Vienna offers the most diverse range of courses in the country.


CO gas detection from MSR-Electronic and MSR-Austria for protection in the event of gas leakages


Many of the University of Vienna’s satellite campuses use gas boilers for heating. In this process, gas is burned to heat water, which is used for heaters and/or hot water. For increased safety in the event of carbon monoxide leakages, gas warning devices from MSR-Electronic Germany were installed in addition.

In this way, increased gas concentrations in the ambient air can be detected as quickly as possible and employees can be warned in time via acoustic signals. All persons are thus requested to leave the rooms immediately.

Carbon monoxide (CO) is a highly toxic, odourless and colourless gas. It is produced during combustion processes, e.g. in a gas boiler. Since carbon monoxide cannot be perceived through the senses, affected persons do not notice when they inhale the toxic gas.





Hence, Multi-Sensor-Controllers (MSC2) with integrated warning buzzer and status LED from MSR-Electronic were installed at approx. 40 locations of the University of Vienna for the secure CO gas detection. The gas measuring devices comply with EN 50271.   MSC2 Controller is a gas measuring, warning and controlling device based on the state-of-the-art micro-technology for continuous monitoring of the ambient air to detect toxic and combustible gases, refrigerants or oxygen.  It is designed for warning against gases in many commercial and industrial applications.


The following features distinguish the MSC2 Controller:

Cost-reduced calibration due to sensor head exchange on site


Thanks to the X-Change technology, calibration can be carried out by simply exchanging the sensor head or by using the integrated, convenient calibration routine directly on the system.
