LTI Criterion™ RD 1000 Dendrometer

This revolutionary measurement device features an integrated tilt sensor which allows collection of diameter data at any point up the stem and also determines the height at which a specific diameter is reached. The Basal Area Factor (BAF) routine indicates "In" and "Out" trees for a full range of sampling factors. In addition, the status of borderline trees can be determined by entering a distance from a rangefinder (not included) into the Criterion RD 1000 through the input serial port or manually via the keypad. A second output serial port allows for data transfer to an external data collector (not included). To improve measurement resolution at greater distances, use the included 2.4x magnifier. The in-scope LED display features variable brightness for easy reading in all lighting conditions. Water and dust resistant, the unit also features a 1/4" x 20 mount for attachment to a monopod or tripod. Carrying case, lens cloth, neck strap, and manual included.
