Frequency Range: 5 Hz – 400 kHz
Meets Swedish MPR Band I and II Requirements. Full ELF and VLF capability to the Swedish MPR and the IEEE 1140 test requirements in a single meter makes low frequency electric field testing quick and simple.
The HI-3638 sensor is fully isolated from the readout device (HI-4416 numeric handheld readout, HI-4460 Graphical Display or HI-4413P Optical Modem) by up to 300 meters of fibre optic cable. To assist users in automating the test session and analysing the test data, ProbeView EMF Analysis Software can be used in conjunction with the HI-3638 when connected with either the HI-4413P.
The instrument demonstrates wide applicability from industrial applications to environments such as near power transmission lines electricity sub-stations.
