Link Microtek is now stocking the new Nardalert S3 RF radiation monitor from Narda Safety Test Solutions.

Featuring an innovative design with removable sensor module, the S3 unit allows rapid support in the field, simplifies calibration logistics and offers a simple means of implementing future upgrades. These are significant benefits for organisations such as broadcast and telecoms companies, which typically operate a large number of monitors to protect personnel working in the vicinity of high-power transmitters.

The frequency response of the sensor module is shaped to match the requirements of the ICNIRP international standard. Should the monitor detect electric field strengths that approach or exceed the specified exposure limit, it will generate visual, audible and vibration alarms to alert the user. The unit’s two alarm thresholds are preset to 50 percent and 200 percent of exposure limit but can be altered to other values if required.

The Nardalert S3 also features a top-mounted colour display, which shows battery status, sensor information and the frequency band of any detected fields.

For more advanced applications, an S3 ‘Optioned’ model provides additional functionality such as storage and display of exposure history and transfer of recorded data via USB or fibre-optic links.

Designed to be worn on the body or used as a fixed area monitor, the Nardalert S3 is housed in a rugged plastic casing measuring just 117.1 x
82.6 x 31.8mm and weighing only 230g with sensor attached.

It is powered by an RCR123A rechargeable lithium-ion battery, which provides approximately 25 hours of operation and can be charged either via a computer’s USB port or using the universal charger supplied.

Each monitor also comes with belt clip, lanyard clip, silicone rubber skin for additional shock protection, USB cable, software, operating manual, calibration certificate and carrying case. Optional accessories include fibre-optic cables and converters, as well as a mounting bracket to facilitate area monitoring.
