VUFM 1670 – Direct Indication E-Field-Meter

The VUFM 1670 is small, lightweight and low priced non frequency selective E-field meter. It can be used for relatively high field strengths e.g. to observe the field in a TEM cell or a strip line. The frequency range covers all kinds of AM, FM and TV transmitters, including CB, amateur radio and cellular nets.
The analog meter VUFM 1670 can be combined with an LCD display unit VUFM 1671. The con-nection is realized using a plastic optical fiber which is connected to the right side of the hous-ing of the VUFM 1670.
