The EHP-50F is a LF analyzer in a particularly compact package, which is equipped with E field and H field sensors for all three spatial dimensions. It can therefore make frequency selective, non-directional measurements of electric and magnetic fields with high accuracy and dynamic range. The built in tripod bush and remote operation via optical cable mean that the EHP-50F can be optimally positioned at the place of measurement without causing distortion in the field due to the presence of any person. Operation can be from a PC using Windows based software or from the Narda NBM-550 basic unit. The EHP-50F can perform fully automatic long-term measurements for up to 24 hours in stand-alone operation, storing the results in the device itself.
