About the MD900-T Biaxial Clinometer

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.
