GaussAlert™ GaussAlert™ is designed to help keep MR Conditional equipment outside of the MRI exclusion zone. GaussAlert™ is programmed to alarm when the preset magnetic field strength is exceeded. It produces an attention-getting audio alarm when MR Conditional equipment is too close to the MRI magnet.

Medical equipment that is used in the MRI room, such as infusion pumps, contrast injectors, patient monitors, anesthesia machines and others may malfunction and potentially injure the patient if not kept outside of a specific magnetic field strength. In addition, MR Conditional equipment can degrade the image quality of a scan if brought too close to the MRI magnet. With GaussAlert™, the possibility of equipment malfunction and image degradation is dramatically reduced.


Worldwide Patented Sensor Technology assures long battery life. The Sensor is 100% mechanical thus the battery power is only used to produce acoustic alarm.
No need to charge the device. No need to replace the battery for at least 5 years.

“The normal or safe operation of many medical devices designed for use in the MR environment may be disrupted by exposure to conditions exceeding the device’s conditional rating threshold. It is advisable for MR facilities to identify the maximum conditional rating for static field and spatial gradient exposure for each MR Conditional device that may be brought into Zone IV.”

GaussAlert™ is available in three factory preset gauss thresholds: 10, 30 and 100 gauss, based on the equipment manufacturer’s specifications

GaussAlert™ easily and quickly attaches to any piece of equipment that goes inside the magnet room.

GaussAlert™ compliments the function of our FerrAlert™ HALO detectors by monitoring equipment that has passed through the portal but still must be monitored inside the magnet room.
