About the C802 Tuff Tilt 420 Deep Water Submersible Tiltmeter

The C802 Deepwater Tiltmeter is a high-precision submersible tiltmeter for use in marine, offshore, and deep ocean applications with 4-20mA output. Using an absolute gravity referenced electrolytic sensor, the C802 delivers superior measurement accuracy with virtually no long-term drift.

High-gain units are sensitive to <0.0017 mm/m or better. All units are rated to +2500m waterproof for advanced protection from the elements.

Use the D802 “DeepWater” for structural monitoring, angle measurement and control, platform leveling, and more.
