The Model 701-2 Platform mount tiltmeter is our most popular design for high precision tilt measurements. Units come with built-in invar leveling legs, for easy installation on any horizontal surface.
The A701-2 also includes two switchable gains and two low-pass filter settings. Using an absolute gravity-referenced electrolytic sensor, the A701 delivers ultra-high sensitivity to <0.1 µrad with virtually zero long-term drift. The output is a stable ±8 DC voltage (±16 VDC differential). The D701 digital version has onboard memory, with a storage capacity of up to 22,000 samples.
