DC measuring amplifier

MESSOTRON miniature DC measuring amplifiers are well suited, for example, for DMS in full, half and quarter bridge circuits. They can be installed in a variety of places and are very space-saving. They can be readjusted at any time using the integrated setting elements.

Carrier frequency-measuring amplifiers suitable for DMS operation can be found at our multi-channel and laboratory measuring amplifiers.
