KAPPABRIDGES FOR MEASUREMENTS
OF MAGNETIC SUSCEPTIBILITY
- IN-PHASE AND OUT-OF-PHASE
- ANISOTROPY
- FIELD VARIATIONS
- TEMPERATURE VARIATIONS
General description
The KLY5 Kappabridges are the most sensitive commercially available laboratory instruments for measuring magnetic susceptibility and anisotropy of magnetic susceptibility (AMS). KLY5 series brings precise absolute measurement of both in-phase and out-of phase components of magnetic susceptibility and anisotropy of magnetic susceptibility.
Versions
KLY5-A
Fully equipped with special Up/Down mechanism and rotator allowing to use spinning specimen method which uses 3D rotator or classic rotator for easy, rapid and precise AMS measurements. Automatic routines for investigation field variations of AMS as well as bulk susceptibility are incorporated for better user comfort. Optional attachments CS4 and CS-L enables measurements of temperature variation of bulk susceptibility from -192°C up to 700°C.
KLY5-B
Basic version of Kappabridge for manual measurements of AMS, bulk susceptibility and field variations of magnetic susceptibility without Up/Down mechanism, rotator and CS4 or CS-L support. To faciliate AMS measurements magnetic susceptibility must be manually measured in 15 different orientations. Can be upgraded to KLY5-A version, but such upgrade has to be done in AGICO facility.
Software
Data acquisition software Safyr controls all particular functions of the Kappabridges, calculate results of individual measurements as well as advanced statistics on measured data. Standard visualisation of the results is also incorporated. For more in-depth analysis of AMS AGICO provides Anisoft - advanced software for processing of AMS datasets.
