Product Description
The IFI EFS-1 E-Field sensor is a highly versatile, low cost test instrument for measuring strong electric fields in the VLF, LF, MF, HF and VHF regions of the spectrum. No tuning, bandswitching or other frequency-related adjustments are required. It is calibrated directly in Volts per meter with four convenient ranges for direct reading of 1 to 300 Volts/meter from 10 kHz to 220 MHz. Because the EFS-1 is physically small and self-contained (powered by two standard nine Volt batteries) its effect on the field being measured is negligible.
FEATURES: E-Field Range: 0 - 300 V/m
Frequency Range: 10 kHz-200 MHz
FULL SCALE RANGE:
Switch Up: Long Antenna - 10 V/m, Medium - 100 V/m, Short - 300 V/m
Switch Down: Long Antenna 3 - V/m, Medium 30 - V/m, Short - n/a
Light Modulator-Transmitter (LMT) is also available for remote reading and control using fiber optic data links to avoid field distortion and erroneous readings due to the presence of conductive interconnecting cables.
Comes With:
- EFS-1
- LMT
- 1 set of 3 antennas - Antenna lengths (rod portion only, not including base) 6-7mm,21mm, 95mm.
- The cable that connects the EFS-1 to the LMT
