Description
The NBM-500 Series is the most accurate non-ionizing radiation survey system
available. It provides the broadest frequency coverage of electric and magnetic
fields. Both flat response probes and probes shaped to international standards
are available. All NBM probes have a non-volatile memory containing device
parameters and calibration data. Probes are calibrated independently of the
meter. Any NBM probe can be used with any NBM-500 Series meter and still
maintain total calibration.
Applications
Precision measurement of electric and magnetic field strength for personal
safety at work where high radiation levels are present, such as:
General RF Safety program measurements
•
Service work on transmitting and radar equipment
•
Service work on mobile antennas, broadcasting and satellite
•
communication systems
Working with heating and hardening machines in the industry
•
Operating diathermy equipment and other medical instruments
•
producing short-wave radiation
Drying equipment in the tanning and timber industries
