Model 900 Biaxial Clinometer

The dual-axis Model 900 is an inexpensive, gravity-referenced clinometer with analog voltage output and compact dimensions. Sold without a housing, its small size and performance make it an excellent choice for many OEM, test, and measurement applications. It is available in high-gain, standard, and wide-angle versions, each with a different angular range. Model 900 accepts a wide input voltage range and provides high-level single-ended outputs that are easily measured with any voltmeter or digital recording system. Viscous damping and temperature measurement are available as options.
