METPOINT® MMA: For the quality of the aer medicinalis

When particle- and oil-free air is required (aer medicinalis), for example 

  • with artificial respiration
  • for inhalation of medicaments
  • for the care of patients at risk of infection

it is the task of the hospital or medical facility to ensure the highest air quality. International standards such as the European Pharmacopoeia, United States Pharmacopeia USP - NF34 and standards for compressed air quality (e.g. ISO 8573 1-9) define the quality of the air and its regular inspection.

While offline methods for controlling medical air are still being described and applied, the MMA compact provides fully automated 24/7 online control of key air parameters. The critical parameters CO, CO2, NO, NO2, SO2, O2 and residual oil content are measured online using electrochemical and photometric sensors and immediately checked for exceeding the limit values. Alarms are automatically generated when limit values are exceeded. With the integrated data logger, all measurements are logged and are available for complete quality control.

For the safety of patients

The strict limit values of medical air are intended to preserve the health of patients and not be endangered by deteriorated air conditions. MMA compact helps those responsible for quality, e.g. in hospitals, to ensure this process and patient safety.

With integrated reference gases, all sensors are automatically calibrated at 24-hour intervals and a corresponding error message is issued in the event of deviations. This regular check ensures high-precision measurement results. Our service is available for on-site maintenance and ensures a reliable system for monitoring the medical air.

Manual sampling and offline laboratory tests are now a thing of the past thanks to MMA Compact.

Our calibration service for your METPOINT® MMA

Transducers and transmitters are exposed to mechanical stress and temperature fluctuations among others. As a result e.g. the measuring accuracy of sensors decreases and generates a so-called “drift”, which then falsifies the measured results and can thereby impair production and product quality. BEKO TECHNOLOGIES provides a comprehensive range of calibration services for volume flow sensors, pressure dew point transmitters, pressure measurement converters and analyses devices. The calibration is executed according to a specified calibration method from BEKO TECHNOLOGIES and is a so-called ISO calibration. ISO calibration is based on reference measurements performed with externally provided test specimens and certified reference devices. All reference devices can be traced back to national standards. The relevant procedures and methods meet the requirements of the DIN EN ISO 9001 quality standard.
