The ISA-60M controller with remote MRI-5175 oxygen sensor/transmitter is specifically designed to continuously monitor for oxygen deficiency in a Magnetic Resonance Imaging (MRI) facility. Maintaining the quality of breathing air in an MRI room 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 the breathing air to unsafe levels. The ISA-60M system ensures the safety of the technicians and patients by continuously monitoring and displaying the levels of oxygen in the room and providing audio and visual alarms when there is an unsafe, low level oxygen condition in the area being monitored. Three verisons available; Single Channel, Dual Channel, and Three Channel.Product Highlights
