The Jewell Instruments A701-2 Platform Tiltmeters are designed for rapid installation and precision. Using a built-in invar leveling legs, they can be set up and operating on any hard horizontal surface. The two orthogonal tilt sensors parallel the right-angle sides of the base plate. Each tiltmeter includes a temperature sensor. The internal electronics drive signals over cable lengths greater than 1000m.

The A701-2 has switchable gain and low-pass filter settings that give you a range of measurement options. Sensors and electronics are mounted in a rugged housing that also provides electrical shielding. Model 701-2 is water resistant for protection against light rain and splashes. It is the preferred choice for structural load testing, volcano monitoring, and laboratory and observatory work.
