Nardalet XT RF personal monitor

The Nardalert XT RF personal monitor, shown here with the pocket clip installed, is the most accurate RF personal monitor and has a number of features exclusive to the monitor. The only simple way to distinguish between models is to look at the label on the back, with the exception of the high-power model that has a unique logo on the front.
The two yellow and three red LED indicators flash in sequence to indicate the strength of the RF field. They are very bright and are able to be seen even in strong sunlight. A photo sensor automatically dims the LEDs when the monitor is used indoors or at night. The positioning of the LEDs on the top of the monitor makes them easy to see when wearing the monitor in your pocket or when using the optional soft case that attaches to a climber’s safety harness.
The High Power model has a different logo on the front to make it easy to identify.

Nardalert XT Monitors

The Nardalert XT is available in 13 models. Seven of these models are suitable for use in the United States and are available from RF Safety Solutions. (We do not sell the models designed to conform to Canada’s Safety Code 6 and the ICNIRP standard.) All the monitors operate from 100 kHz to 100 GHz except for the 8861 series.

Available Models


The Nardalert XT has two different types of mounting clips that are standard and two types of optional soft cases. One of these soft cases is designed to attach to a safety harness. There have been countless numbers of monitors dropped while climbing towers, and this is by far the best solution available to securely attach a monitor while climbing. You should not climb a tower without this inexpensive accessory.

The Model 8865 Interface Kit is used to download and analyze logged data. If data logging is important to you, you will need one of these kits. You only need one kit even if you have several monitors.

The Nardalert XT data sheet provides complete specifications.
