The Jewell Instruments A711-2 / A716-2 Tiltmeter are precision biaxial tiltmeters that bolt or clamp to any surface and are well suited for areas of heavy traffic or vibration. They are identical to the Model A701-2 Platform Tiltmeter, but have 0.5 inch (12.7mm) diameter holes in their three corners instead of adjustable legs. The holes fit over threaded stainless steel studs. The tiltmeter is double-nutted to the studs after they have been firmly anchored in the mounting surface.

The internal electronics of Models A711-2 and A716-2 will drive cable lengths of 1000m. These tiltmeters are widely used for structural monitoring, load testing, and precision alignment of antennae and machinery.
