Electric & Magnetic Field Spectrum Analysis
Here's a neat combination meter which affordably gives both frequency and field strength information for low frequency electric and magnetic fields. Hand held and completely self contained, with a huge LCD display. Includes rechargeable battery and input for external DC power supply. Great price too!
• Superfast FFT spectrum analysis
• 3 axis magnetic field measurement
• Frequency and signal strength display!
• High-resolution multi-function display
• Exposure limit calculation!
• Typical accuracy: 5%
• Audio output with volume control
Comparing readout against established exposure limits:
Exposure limit calculation can be a complex and awkward procedure even for the professional, as most of the time a chaotic mixture of different frequencies, modulations and signal strengths is present.
Not so with SPECTRAN® units: They can calculate several authoritative exposure limits, precautionary limits and recommendations at lightning speed (simply select which limit you want via a button) and display the measured levels as a % of the selected limit and a practical bargraph display.
