The Jewell Instruments A711-2 (4X) Weatherproof Tiltmeter is the weatherproof version of the A711-2 Floor Mount Tiltmeter. Its NEMA 4X designation (IP65) means that it is unaffected by continuous exposure to moisture and wet weather, and that it resists corrosion that can occur in wet conditions. The tiltmeter also measures temperature, and the internal electronics will drive tilt and temperature signals over cable lengths greater than 1000m.

The A711-2(4X) bolts or clamps to any surface and is well suited for areas of heavy traffic or vibration. The 0.5 (12.7mm) inch holes in its three corners fit over threaded stainless steel studs, provided with each order. The tiltmeter is double nutted to the studs after they are anchored in the mounting surface. Applications include volcano monitoring, precise alignment of telescopes and antennae, monitoring of large structures, and all jobs demanding top performance under harsh operating conditions.
