Application: |
Wide range of application
for your home, job and hobby, e.g.: - Bio chemistry: Oxygen monitoring an breeding
chambers for cell cultures.
Monitoring of fermenting process fo fruits infermentation plants etc.
- Medicine: Monitoring of oxygen concentration in
respirators; checking of breathing, gmh369
monitoring of oxygen concentration in incubators, oxygen tents etc.
- Food technology: Monitoring of residual
oxygen in packages (e.g. coffee, tea, etc.).
Monitoring of oxygen content during production processes
- Safety technology, safety at work: Oxygen
monitoring in mines/pits, underground parking lots,
wine cellars,
cooling chambers, greenhouses or stores.
Oxygen
monitoring or alarm in case of danger of suffocation when working in tanks,wells
etc.
- Air conditioning and ventilation technolgy:
Oxygen measurements, air quality monitoring,
measuring of
oxygen concentration in enclosed air conditioning systems, etc.
- Sports: Checking of oxygen conent in compressed
air breathing apparetuses (diving, etc.)
oxygen
monitoring for gliding.
