The biaxial model MD900-T is an economical digital
clinometer with powerful firmware features. User
programmable settings include AUTO-zero (tare),
baud and output rate, sample averaging, and more.
Output is RS232 or RS422 (RS485 full duplex). The
MD900-T easily integrates with a variety of GPS
receivers, and supports Trimble TCM, NMEA XDR,
BAE, and Ashtech output protocols. Units ship
standard with 6-ft. hook-up cable and 100-240VAC
power transformer. Use the MD900T for industrial
pitch and roll measurement, marine piling, dredging
and construction systems, platform leveling,
geotechnical monitoring and more.
