Oxyplus Technologies Gas Analyser Pharmagas

PHARMAGAS medical gases quality analyzer is designed to measure continuously the quality of medical air and/or oxygen injected in the hospital medical gas piping network.

For patients safety, it provides a complete traceability of the medical gases quality, and guarantees their compliance with all current regulations (European pharmacopeia or other local regulations).

It can be connected nearby the medical gases distribution or production system, or anywhere in the hospital where a medical gas outlet is available. 

PHARMAGAS is designed on a modular base and can be adapted to your specific needs, depending on the analyzers you need. 

Main module components

  • Carbon monoxyde analyzer (CO)
  • Carbon dioxyde analyzer (CO2)
  • Pressure and flow regulators, pneumatic connexions
  • High resolution color touch screen panel, which displays the measured values, makes the instant comparison of thresholds in accordance with current regulations, and assures the continuous values recording on memory cards (files generated on Excel™ format), with graphical representation of historical curves. The alarms history is recorded as well.

Additional analyzers

All additional analyzers are integrated to the main module, and the tactile screen displays the value measured for each analyzer. 

  • Hygrometer (dew point / water content measured in °C or in PPM)
  • Oxygen analyzer (O2)
  • Nitrogen oxide (NOx)
  • Sulfur dioxide analyzer (SO2)


  • TCP/IP Module for an offset checking via Internet or a local computer network 
  • GSM Modem for the alarm default reporting on mobile phone, via text messages (SMS)
