The Narda Nardalert XT D8862 Personal RF Monitor is designed to satisfy the needs of virtually all individuals who use an RF personal monitor. The Narda Nardalert XT D8862 is worn on the body to detect higher levels of radiation. The ultra-broadband sensors of the Narda Nardalert XT D8862 cover almost the entire usable RF spectrum in a single monitor with a frequency range of 100 kHz to 100 GHz.
The unique tri-sensor design of the Nardalert XT D8862 handles every possible signal format, from complex multi-signal communication environments to military platforms with both communications and radar signals.
The Nardalert XT D8862 closely conforms to AS/NZ 2772.1 (1998, draft) Occupational; DIN VDE 0848, Part 2, October 1991 Area 1 Occupational; ENV 50166-2 Occupational; and ICNIRP 1998 Occupational standards. The five flashing high-intensity LED level indicators can be seen while wearing the monitor, even outdoors in the sun. The adjustable alarm feature allows one alarm to be set at a level equal to the upper tier of two-tier standards, such as the “Occupational” or “Controlled” limits, while the second alarm can be set to the lower tier, such as the “Action” or “General Population” limits.
The audio alarm has two distinct sounds that are associated with the two different alarm thresholds. The user can select an audio alarm, a vibrator alarm, both audio and vibrator, or an optional remote vibrator. The remote vibrator on the Nardalert XT D8862 can be used in areas with high ambient noise when the user is wearing heavy clothing that would prevent the detection of the internal vibrator.
