ETS-Lindgren's Model HI-3638 VLF/ELF Electric Field Meter is a EMF meter that has full ELF (extremely low frequency) and VLF (very low frequency) capability to the Swedish MPR and the IEEE 1140 test requirements in a single meter, making electric field testing quick and simple.

The HI-3638 sensor is fully isolated from the readout device (HI-4416 numeric handheld readout or HI-4413USB Optical Modem) by up to 100 meters of fiber optic cable. To assist users in automating the test session and analyzing the test data, ProbeView™ II EMF Analysis Software can be used in conjunction with the HI-3638 when connected to a PC. 

The instrument demonstrates wide applicability from low field measurements higher field environments such as near power transmission lines and industrial locations.

NOTE: Tripod not included.
