The Swoffer Model 2100 and Model 3000 are hand held, portable instruments for measuring open stream velocities in feet or meters per second. Both models feature weatherproof construction, digital display, self-calibration and a measurement range of 0.1 to 25 feet per second. Each model is sold with your choice of measurement wand, complete with 2" glass-filled nylon propeller and PVC jacketed cable that is equal to the length of the fully extended wand plus 5 ft. Accuracy for both models is ۫% of reading. The Model 2100 features a digital display with maximum/minimum velocity, three preset averaging times of 5, 20, and 90 seconds and a start/stop button for interval testing. Uses one 9V battery, included. The upgraded Model 3000 is a computer/datalogger version of the Model 2100, allowing on-site computation of stream discharges. The easy to use keypad allows you to input key information such as velocity angles, velocity averaging period and units of measurement. The computer memory stores calibration data, calculates accumulated discharge, stamps data with month, day, year & time plus allows all stored information to be downloaded via the RS-232 output. Up to 1000 "stations" can be stored in memory.
The unit is sold complete with the required download cable and software. Uses four AA bateries (included).
