The model A904 “Clinometer Pak” is a low cost
biaxial inclinometer housing a rugged weather­proof enclosure. Units are available in +/-2.5V
or 0-5V DC output. All A904 Clinometers are
IP65 waterproof, and powerful on-board
electronics will drive cables over 500 meters.
Use the model A904 and for industrial pitch and
roll measurements, platform position and
control, geotechnical monitoring and more.
Units come standard with 3m cable pigtail; for
longer lengths please specify per order.
