Monitoring gas concentrations


Gassen meten

Aurolex can be connected to a total of 9 analog sensors 0-10V or 0-20mA output. With a special extension module, Aurolex can wirelessly connect to as many as 256 analog sensors.

Increased attention to energy saving measures has also increased awareness of the risks an unhealthy indoor environment can present An important parameter for measuring air quality is CO2 concentration in the air. This is  an especially important area of focus in schools and hospitals. When CO2 concentrations monitored with the Aurolex exceed a certain level, an alarm is triggered and notification is sent to one or more users via SMS or email. The Aurolex system can monitor CO2 levels continuously in an indoor environment.

Health, Safety and Building Regulation requirements for indoor environments in non-industrial work situations need only meet minimum standards to reduce risk of serious effects to employees However, compliance with these requirements does not guarantee overall satisfaction or a comfortable working environment. The research institute Foundation Building Research (FBR) makes a distinction between indoor requirements where the lowest class is virtually identical to the statutory requirements. Three classes of air quality are organized as follows and are based on the ISSO / SBR 354 and NPR CR 1752:

Class A: 'very good' - high expectations regarding the quality of the indoor
Class B: 'good' - average expectations regarding the quality of the indoor
Class C: 'acceptable' - moderate expectations regarding the quality of the indoor environment, minimum required by public health officials
