Narda SMARTS Surveillance Monitor | 2 MHz - 100 GHz

Discontinued
The Narda SMARTS Surveillance Monitor has been discontinued.
The Narda SMARTS Surveillance Monitor, 8820 provides continuous detection of radio frequency (RF) radiation within a specific area. Narda 8820 models can cover any frequency between 2 MHz and 100 GHz. These monitors represent an advance in safety monitoring programs for non-ionizing radiation. A safety program was once limited to performing periodic surveys of a particular system or area, which meant an acute failure could go unnoticed until the next survey. 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 Narda SMARTS 8820, potentially hazardous areas can be continuously monitored to help insure a hazard-free environment as well as compliance with industry and government standards.

Narda 8820 (500 MHz to 18 GHz) and 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 the SMARTS from dust, rain, or heavy seas.

The Narda SMARTS Surveillance Monitor, 8820 is part of the Narda Safety Test Solutions SMARTS Series.

Notes:
a Peak to peak. The threshold can be factory set to provide optimum performance over a specific band of interest.
b 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 Permissible Exposure (MPE) from 3 to 30 MHz and equal to 10% of the E field MPE from 2 to 30 MHz.
(Controlled Environments)
c 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
mounting plane.
d The rated life is two years. It is recommended that this battery be replaced annually during calibration.
e 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.
f Other calibration frequencies available for narrow band applications. Contact the factory.
