The model 900 Biaxial Clinometer is an
inexpensive, gravity-referenced clinometer
(tiltmeter) with a wide dynamic range. Its small
size and high precision make it a versatile
choice for many measurement and control
applications. Units are available with +/-2.5V or
0-5V DC output. Custom calibration ranges are
also available on request. Units ship standard
with 18” hook-up cable. Use the model 900 for
industrial pitch and roll measurements,
platform position and control, OEM assemblies,
specialized research applications, and more.
