Radman 2 low cost EMF personal monitor

The Radman 2 LT is is a brand new low-cost personal EMF safety monitor, it offers the accuracy and quality of tried-and-tested technology, together with several new features and well-thought out ergonomics.

Radman 2Designed to alert workers to the presence of strong electromagnetic fields, the new monitor covers frequencies up to 8GHz and is manufactured in Germany by the world leader in EMF safety, Narda Safety Test Solutions. It draws on the heritage of the original RadMan personal monitor and is primarily aimed at those who carry out installation, maintenance or troubleshooting work on telecoms or broadcast antenna masts.

Capable of delivering 800 hours of operation from a single charge of the standard NiMH batteries, the monitor executes an automatic sensor test at switch-on to provide peace of mind that it is functioning correctly. It comes with a holder and strap for easy mounting on a climbing harness, plus a strong elastic cord for use out of the holder. Operation of the monitor is straightforward and intuitive. Should an alarm threshold be exceeded, the wearer is warned by an effective combination of vibration alert, audio alarm and an extremely bright alarm indicator light, which is built into the top part of the device and clearly visible from most angles, ideal for use when climbing. With its simultaneous E-field and H-field monitoring capability, the RadMan 2LT provides reliable warnings regardless of the distance from the field source.

Narda’s patented shaped frequency response technology enables measurements to be displayed as a simple percentage of the EMF Directive or CEMFAW Regulations Action Level. The alarm threshold is matched over the entire frequency range, so there is no need to adjust it according to the frequency of the field source. The actual field exposure level is indicated by LEDs in six steps from 5% to 200%, with the alarms activated if the level exceeds 50% of the limit value. If the 100% threshold is reached, a second, more persistent alarm sounds to warn the user to leave the danger area. A built-in data logger enables the user to record time-stamped values of E-field and H-field measurements, while a USB-C interface allows rapid transfer of data to a PC for analysis using the freely downloadable RadMan 2-TS software. 

Housed in a robust, weatherproof IP65-sealed casing, the RadMan 2LT weighs just 185g and can be used in ambient temperatures from -10 to 55degC. Calibration is only required every 3 years. Also available is a companion product, the RadMan 2XT, which provides frequency coverage all the way up to 60GHz and is therefore suitable for upcoming 5G applications.
