GMM software
-
GMM, our in-house gas analysis management software, has been developed specifically for Fresenius Umwelttechnik measurement systems.
The programme offers a great variety of features via a serial communication interface. These include, for example, real-time recording of measurement data or automatic data downloads from the measurement systems’ internal memories.
The recorded measurement values can be saved as a file or in an integrated SQL database. What is more, you may create both tabular and graphic data evaluations. These will help you monitor and optimise your processes.
An integrated encoding method ensures the data’s protection against forgery so that they are also suitable for submittal to authorities.
Besides, qualified personnel trained and authorised by us will be given access to further features such as the analyser’s calibration and configuration or commands.
We will be happy to advise you and provide you with further information on our GMM software.
