Introduction

The Digi-Sense Data Logging Anemometer

(Model 20250-22) measures air velocity within a range of

1.1 to 20.0 m/s and records up to 32,000 readings. Sam-

pling rate, high/low alarm levels, and start mode can be

deﬁned by the user with the Windows®98, 2000, XP, Vista

and Win 7 compatible software provided. Logged data is

downloaded to a computer via the integrated USB interface

for analysis, graphing, and print out. The instrument is fully

tested and calibrated to NIST-traceable standards. Careful

use of this meter will provide years of reliable service.
