ISA-60M Oxygen Monitor
1-3 Channels with Remote MRI-5175 O2 Sensor/Transmitter
Oxygen Monitor Alarm for MRI Installations
Maintaining the quality of breathing air in a Magnetic Resonance Imaging (MRI) facility is an important safety consideration. Cryogenic gas used to maintain the magnetic field is highly dangerous if released into an enclosed space. Inert gas can create a hazardous situation by reducing the concentration of oxygen in breathing air to unsafe levels.
The silent, odorless, and invisible hazard of low oxygen concentrations can incapacitate or even kill. Reduced oxygen levels start by causing fatigue, confusion, and disorientation without individuals being aware of their peril. If oxygen levels are further reduced, fatalities may result in minutes.
