The ultra-broadband sensors cover almost the entire usable RF spectrum in a single monitor. The unique tri-sensor design handles every possible signal format, from complex multi-signal communication environments to military platforms with both communications and radar signals.

The five flashing high-intensity LED level indicators can be seen while wearing the monitor, even outdoors in the sun. There are four different ways to wear the monitor – pocket clip, belt clip, soft case with belt clip (optional) and soft case for climber’s harness (optional). The audio alarm has two distinct sounds that are associated with the two different alarm thresholds. Both alarm thresholds can be adjusted using the optional Interface Kit. Models are available that closely conform to all major worldwide standards. The adjustable alarm feature allows one alarm to be set at a level equal to the upper tier of two-tier standards, such as "Occupational" or "Controlled" limits, while the second alarm can be set to the lower tier, such as the "Uncontrolled" or "General Population" limits.

The new Nardalert XT family of RF personal monitors is designed to satisfy the needs of virtually all individuals who use an RF personal monitor.
