Electrolytic tiltmeter for geophysical and geotechnical applications


About the 820 Shallow Water Submersible Tiltmeter

The 820 Shallow Water is a high-precision submersible tiltmeter for use in fresh and salt water applications. Using an absolute gravity referenced electrolytic sensor, the 820 delivers superior measurement accuracy with virtually no long-term drift. High-gain units are sensitive to <0.0017 mm/m or better.

Output options include analog (±5 VDC, ±10 VDC), current (4-20mA) and digital (RS232 and RS422). All units are rated to 50 meters waterproof for advanced protection from the elements. Use the 820 “Shallow Water” for structural monitoring, angle measurement and control, platform leveling and more.
