The Model 801 “Tuff Tilt” Tiltmeter series combines high precision and durability in an economical instrument package. Using an absolute gravity referenced electrolytic sensor, the 801 series delivers superior measurement accuracy with virtually no long-term drift. Units are available in a variety of configurations including single axis (uniaxial), or dual axis (biaxial), analog, digital, or 4-20mA outputs.
All units are rated IP65 waterproof for advanced protection from the elements.
