The KLY-4S Spinner and KLY-4 Kappabridges are the worlïs most sensitive commercially available laboratory instruments for measuring anisotropy of magnetic susceptibility (AMS) as well as bulk susceptibilty in weak variable magnetic fields.

General Description

The KLY-4/4S Kappabridge consists of the pick-up unit and control unit connected with PC computer via RS-232C.

In principle the instrument represents a super-precise fully automatic inductivity bridge. It is equipped with automatic zeroing system (in both real and imaginary components) and automatic compensation of the thermal drift of the bridge unbalance as well as automatic switching of appropriate measuring range. The measuring coil is designed as 6th-order compensated solenoid with an outstanding field homogeneity.

The digital part of the instrument is based on microelectronic components, with the microprocessor controlling all the Kappabridge functions.

   KLY-4S Kappabridge
Spinner/Static combination

The KLY-4S Spinner model measures the AMS of a slowly spinning specimen. One has to adjust the specimen only in the three perpendicular positions. The measurement is rapid (about 2 minutes per specimen) and precise, profiting from many susceptibility determinations in each plane perpendicular to the axis of specimen rotation.
