Jewell Model MD900-T Digital Clinometer Description：

Datasheet User Manual Outline Drawing

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 RS-232 or RS-422 (RS-485 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 a 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.
