Nardas SMARTS family of area monitors provides continuous detection of RF radiation within a specific area. Models are available to cover any frequency between 2 MHz and 100 GHz. These monitors represent a major advance in safety monitoring programs for non-ionizing radiation. In the past, a safety program was limited to performing periodic surveys of a particular system or area, which meant an acute failure could go undetected until the next survey was performed. And since all major international safety standards set limits for average exposure level over a few minutes, the use of survey instruments alone meant a hazardous condition could exist for days, weeks, or even months. With the SMARTS, potentially hazardous areas can be continuously monitored to help insure a hazard-free environment as well as compliance with industry and government standards.
Model 8820 (500 MHz to 18 GHz) and Model 8825B (500 MHz to 100 GHz) use broadband thermocouple detectors to monitor the electric field. Both models sound an alarm only when the average power level is exceeded and are ideal for use with microwave systems where pulse modulation is normally employed.
SMARTS monitors are available in a totally nonmetallic, weatherproof enclosure for outdoor mounting. This enclosure will protect theSMARTSfrom dust, rain, or heavy seas.

Peak to peak. The threshold can be factory set to provide optimum performance over a specific band of interest.
The alarm threshold is proportionate to IEEE C95.1-1991 Standard and varies over the 2 to 30 MHz band. The threshold is 0.9% of
the H field Maximum Permissable Exposure (MPE) from 3 to 30 MHz and equal to 10% of the E field MPE from 2 to 30 Mhz.
The 3 dB intercept angle is >180° with the E field tangential to the mounting plane and >165° with the E field perpendicular to the
The rated life is two years. It is recommended that this battery be replaced annually during calibration.
The fail-safe battery has a rated life of 5 to 10 years. It is recommended that it be checked annually during calibration and replaced
every three years.
