horizontal intensity variometer horizontal intensity variometer[‚här·ə′zänt·əl in′ten·səd·ē ‚ver·ē′äm·əd·ər] (engineering) Essentially a declination variometer with a larger, stiffer fiber than in the standard model; there is enough torsion in the fiber to cause the magnet to turn 90° out of the magnetic meridian; the magnet is aligned with the magnetic prime vertical to within 0.5° so it does not respond appreciably to changes in declination. Also known as H variometer. |
